Indian and Oriental Architecture, and the Works of Renowned Architects
2. The Hindu temple: Nagara, Dravida and Vesara
A Hindu temple is a house for the deity and a model of the cosmos. Its core is the garbhagriha, a small dark sanctum. In front of it come the antarala (vestibule) and the mandapa (pillared hall), sometimes with a porch (ardha-mandapa); around the sanctum may run a circumambulatory path (pradakshina patha). Over the sanctum rises the tower, called shikhara in the north and vimana in the south. The plan is laid out on the square grid of the Vastu Purusha Mandala, and the temple usually stands on a raised platform (jagati).
| Feature | Nagara (north) | Dravida (south) | Vesara (Deccan, mixed) |
|---|---|---|---|
| Tower | Curvilinear shikhara crowned by an amalaka and a kalasha (rekha deul in Odisha) | Pyramidal vimana of diminishing storeys topped by a domed crown | A blend of the two: tiered towers on star-shaped or many-cornered plans |
| Gateway and court | No great gateway; the sanctum tower is the focus | Walled enclosure with huge gateway towers (gopuram), tank and pillared corridors | Usually a single star-shaped shrine raised on a platform |
| Examples | Lingaraja (Bhubaneswar); Kandariya Mahadeva (Khajuraho); Konark Sun Temple; Modhera | Shore Temple (Mamallapuram); Brihadisvara (Thanjavur); Meenakshi (Madurai) | Chennakesava (Belur), Hoysaleswara (Halebidu), Keshava (Somnathpur); Pattadakal |
Nagara temples span Odisha (Lingaraja, with its rekha deul, jagamohana porch and halls in sequence; the Sun Temple at Konark, planned as a stone chariot, of the thirteenth century), Khajuraho (the Chandela temples, in which the towers rise as clustered, ascending peaks), and Gujarat and Rajasthan (Modhera Sun Temple; the white-marble Jain temples at Dilwara, Mount Abu). Dravida architecture grew through the Pallavas (the monolithic rathas and Shore Temple at Mamallapuram, the Kailasanatha at Kanchipuram), the Cholas (Brihadisvara at Thanjavur, built under Rajaraja I and consecrated about 1010, with a vimana of thirteen tiers) and the Nayakas (Meenakshi temple, Madurai, famed for its gopurams). The Kailasa temple at Ellora, a Rashtrakuta work of the eighth century, is Dravida in form and is carved out of a single rock from the top downwards.
Vesara, the Deccan blend, is clearest in the Chalukyan temples at Pattadakal, where both Nagara and Dravida towers stand, and in the Hoysala temples of Belur, Halebidu and Somnathpur. The Hoysala shrine is star-shaped in plan, rises on a platform (jagati) with a path round it, is built of fine-grained soapstone, and carries dense sculpture and lathe-turned pillars.
3. Indo-Islamic and Mughal architecture
Islamic rulers brought arched, vaulted and domed construction with lime mortar; Indian craftsmen supplied stone carving. Early work in Delhi used the corbelled (false) arch, built of overlapping courses. The true arch of wedge-shaped voussoirs and the true dome become established in the Khalji period, and the Alai Darwaza (1311) of Alauddin Khalji at the Qutb complex is the classic example. A mosque has a courtyard (sahn) with an ablution tank, a prayer hall (liwan) whose rear wall faces Mecca (the qibla wall) and carries the niche (mihrab), a pulpit (minbar) and minarets.
| Phase | Character | Examples |
|---|---|---|
| Delhi Sultanate | Sandstone and marble; corbelled arches giving way to true arches; Tughlaq work with battered, sloping walls and austerity; Lodi octagonal tombs in gardens with double domes | Qutb Minar (begun by Qutbuddin Aibak; about 72.5 m, five tapering storeys); Quwwat-ul-Islam mosque; Alai Darwaza; Tomb of Ghiyasuddin Tughlaq |
| Provincial | Local fusion: Gujarat’s Hindu and Jain carving, Jaunpur’s massive gateways, Deccan domes | Sidi Saiyyid’s jali, Ahmedabad; Atala Masjid, Jaunpur; Gol Gumbaz, Bijapur, with its immense dome and whispering gallery; Charminar, Hyderabad |
| Mughal | Persian garden planning (charbagh), double domes, red sandstone then white marble, pietra dura, jalis, chhatris | Humayun’s Tomb; Fatehpur Sikri; Itimad-ud-Daulah; Taj Mahal; Red Fort and Jama Masjid, Delhi |
Mughal architecture matured in four reigns. Humayun’s Tomb in Delhi (begun in the 1560s, designed by the Persian architect Mirak Mirza Ghiyas) is the first great garden tomb: a charbagh, a double dome, red sandstone relieved with white marble. Under Akbar, Fatehpur Sikri (1571–85) fused Persian, Gujarati and Rajput elements in red sandstone, with the Buland Darwaza, the Jama Masjid, the Diwan-i-Khas with its central pillar and the white-marble tomb of Salim Chishti. Under Jahangir, the Itimad-ud-Daulah tomb used white marble and pietra dura. Under Shah Jahan, the Taj Mahal (begun 1632) stands on a plinth by the Yamuna in a charbagh, with a double dome, four minarets and a pishtaq (arched portal) of white Makrana marble inlaid with semiprecious stones; he also built the Red Fort and the Jama Masjid in Delhi. Under Aurangzeb came the Badshahi Mosque in Lahore and Bibi ka Maqbara, a smaller echo of the Taj.
4. Rajput, vernacular and colonial architecture
Rajput architecture (Rajasthan, fifteenth to eighteenth centuries) answers the desert and the hill. Its marks are hill forts (Chittorgarh, Kumbhalgarh, Amer, Jaisalmer); palaces with jharokhas (projecting balconies), chhatris (domed pavilions) and jalis (stone lattices that screen and cool); courtyard havelis with painted walls (Shekhawati); and stepwells (baoli or vav), an older western Indian form shared by Rajasthan and Gujarat, as at Rani ki Vav, Patan, and Chand Baori, Abhaneri. Jaipur, founded in 1727 by Sawai Jai Singh II and planned with the help of Vidyadhar Bhattacharya, is a grid of nine blocks (chaukris) laid out on Vastu principles, with the Jantar Mantar observatory.
| Region | Building form | Reason |
|---|---|---|
| Kerala | Timber houses with steep roofs, deep eaves and an inner court | Heavy rain and humidity |
| Rajasthan, Gujarat | Inward-looking courtyard havelis and the pols of Ahmedabad, tight clusters with jalis and shaded lanes | Hot dry heat, community and security |
| Himalaya | Kath-kuni: layers of timber and stone laid alternately | Cold climate and flexibility against earthquakes |
| Bengal, coast | Thatched huts with curved eaves, the origin of the bangla roof | Monsoon rain shed quickly |
| North-East | Bamboo and timber houses raised on stilts | Flood, damp and animals |
Colonial architecture came in layers. The Portuguese built Baroque churches in Goa (such as the Basilica of Bom Jesus), the French laid out Pondicherry on a grid, and the British moved from Palladian and Neoclassical government houses through Victorian Gothic Revival to Indo-Saracenic, which put Mughal, Hindu and Gothic motifs on a Western plan. Examples are the Chhatrapati Shivaji Terminus (Victoria Terminus), Mumbai, by F. W. Stevens; the Victoria Memorial, Kolkata, by William Emerson; the Gateway of India, Mumbai, by George Wittet; and the Mysore Palace by Henry Irwin. New Delhi, inaugurated in 1931, was planned by Edwin Lutyens with Herbert Baker: Lutyens designed the Viceroy’s House (now Rashtrapati Bhavan), whose central dome recalls the Buddhist stupa and which uses chhajjas, jalis, chhatris and the “Delhi Order” column capital hung with bells, while Baker designed the Secretariat blocks.
5. Oriental architecture: China, Japan, the Islamic world and Southeast Asia
| Tradition | Structural idea | Key examples |
|---|---|---|
| China | A timber post-and-beam frame carries the roof; walls are non-load-bearing. The dougong bracket sets between column and roof beam spread the load and carry deep, upturned eaves. Courtyard planning on a north-south axis, hierarchical; modules codified in the Yingzao Fashi (1103, Song) | Forbidden City, Beijing (Ming); Temple of Heaven; Foguang Temple (857), a Tang timber hall among the oldest surviving; pagodas, descended from the Indian stupa |
| Japan | Timber post-and-beam with joinery, deep eaves, raised floors, sliding screens (shoji, fusuma), a veranda (engawa), and the tatami mat as the module of rooms | Ise Jingu, a Shinto shrine rebuilt every twenty years; Horyu-ji, Nara; Katsura Imperial Villa; tea houses; Himeji Castle |
| Islamic world | Courtyard mosque, hypostyle prayer hall, iwan (vaulted portal), minarets; domes on squinches or pendentives; non-figural decoration of arabesque, geometry, calligraphy and muqarnas (honeycomb vaulting) | Dome of the Rock, Jerusalem (691–692); Great Mosque of Córdoba, with double-tiered arcades of striped arches, the lower tier of horseshoe form; Alhambra, Granada; Selimiye Mosque, Edirne, by Sinan; Imam Mosque, Isfahan |
| Southeast Asia | Indian-derived sacred forms re-imagined: the temple as a mountain or a mandala, built of sandstone or volcanic stone | Angkor Wat, Cambodia; the Bayon at Angkor Thom; Borobudur and Prambanan, Java |
Angkor Wat was built in the early twelfth century by the Khmer king Suryavarman II as a temple of Vishnu. It is a temple-mountain, a model of Mount Meru, with a moat, concentric galleries carrying long bas-reliefs, and five towers (a central one and four at the corners). Borobudur in Java, a Buddhist monument of the eighth and ninth centuries built under the Shailendra dynasty, is a stupa-mandala without interior chambers: pilgrims climb round six square terraces, with relief galleries, to three circular terraces carrying 72 perforated stupas (32, 24 and 16 in three rings), each housing a Buddha, around a great central stupa. The tatami is about 0.9 m by 1.8 m (sizes differ by region), so one mat is about 1.62 m² and an 8-mat room is about 13 m².

Chandigarh was planned in the 1950s by Le Corbusier, after an earlier plan by Albert Mayer and Matthew Nowicki, and with Pierre Jeanneret, Maxwell Fry and Jane Drew. The city is divided into sectors, each a self-contained neighbourhood of 800 m by 1200 m, separated by arterial roads; at its head stands the Capitol Complex of the Legislative Assembly, the High Court, the Secretariat and the Open Hand monument. Worked example: a sector of 800 m × 1200 m has an area of 960,000 m², which is 96 hectares.
Key takeaways
- Indus cities were planned on a grid with citadel and lower town and covered drains. The Buddhist stupa is a solid relic mound with harmika, yashti, chhatra, vedika and torana; the chaitya is the apsidal prayer hall and the vihara the monks’ residence.
- Nagara has a curvilinear shikhara with amalaka; Dravida has a pyramidal vimana and huge gopurams in a walled court; Vesara is the Deccan blend, with the Hoysala star-plan temple on a platform. Know Konark, Khajuraho, Thanjavur, Madurai, Pattadakal and Belur.
- Indo-Islamic building is arcuated: corbelled arches gave way to true arches and domes, as in the Alai Darwaza. The Mughal line runs from Humayun’s Tomb (charbagh, double dome) through Fatehpur Sikri to the Taj Mahal in white marble with pietra dura.
- Rajput work is forts, jharokhas, chhatris, jalis, havelis and stepwells, with Jaipur’s nine-block plan. Vernacular forms answer climate. Colonial work moved to Indo-Saracenic, and Lutyens and Baker built New Delhi.
- Chinese buildings rest on a timber frame with dougong brackets; Japanese rooms are modulated by the tatami; Islamic buildings use courtyard, iwan, dome and muqarnas; Borobudur (Java, Buddhist, 72 perforated stupas) is not Angkor Wat (Cambodia, Hindu).
- Match architect to idea and safe works: Le Corbusier (five points, Chandigarh), Wright (organic), Mies (less is more), Gropius (Bauhaus), Aalto (humane), Kahn (served and servant; IIM Ahmedabad), Gaudí, Utzon, Niemeyer, Piano, Foster, Gehry, Hadid, Koolhaas, and Doshi, Correa, Kanvinde, Rewal, Laurie Baker and Bawa.

Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.
A Bronze Age city has a raised citadel and a lower town on a rectilinear grid of streets, standardised baked bricks and covered street drains. It is most likely a city of the
Show answer
Answer: A — Indus (Harappan) civilisation, such as Mohenjo-daro
The citadel and lower town, the grid, the standard baked brick and the covered drains are the hallmarks of the Harappan cities. The later empires named in the other choices built very differently: the Mauryas used timber and polished stone, Vijayanagara has stone temple streets, and the Sultanate has arcuated, battered-wall forts.An early Buddhist rock-cut hall has a nave and aisles divided by a colonnade, an apsidal end with a small stupa, a ribbed barrel-vaulted roof and a horseshoe-shaped window over the entrance. It is a
Show answer
Answer: C — chaitya hall, the prayer hall of the rock-cut tradition
An apsidal hall with a colonnade, a stupa at the end and a horseshoe window is a chaitya hall, as at Karla. The vihara is the monks’ dwelling with cells, the stupa is the solid mound itself, and the mandapa is Hindu.A temple stands in a walled enclosure with tall gateway towers, a tank and pillared corridors, and its sanctum is capped by a pyramidal tower of diminishing storeys. The style is
Show answer
Answer: B — Dravida, because it has a pyramidal vimana and a gateway-towered court
The pyramidal vimana and the gopuram-gated walled court with a tank are the signature of the Dravida style of the south. Nagara temples have curvilinear shikharas and no great gateway towers.A twelfth-century temple in Karnataka is built of soapstone, stands on a platform with a path round it, and has a star-shaped plan with lathe-turned pillars. Which of the three classical temple traditions best labels it?
Show answer
Answer: D — Vesara, the Deccan blend, of which the Hoysala star-shaped temple is the clearest case
A soapstone, star-plan temple on a jagati with lathe-turned pillars is the Hoysala type of Karnataka, the usual example of the Deccan blend called Vesara. It is not Nagara or Dravida in the strict sense; the other choices each attach a false reason to a familiar name.Which structural advance over the earlier corbelled work is classically shown by the Alai Darwaza of 1311 at the Qutb complex?
Show answer
Answer: C — The true arch and true dome of wedge-shaped voussoirs
The Alai Darwaza of Alauddin Khalji is the classic early Indian example of the true arch and dome built of voussoirs. The corbelled arch is the earlier, false arch that the true arch came to replace; the ribbed vault with flying buttresses is Gothic and the hypostyle hall is Egyptian.The first great garden tomb of the Mughals, set in a charbagh, with a double dome of red sandstone relieved with white marble, designed by Mirak Mirza Ghiyas, is
Show answer
Answer: B — Humayun’s Tomb in Delhi, begun in the 1560s
Humayun’s Tomb is the first great Mughal garden tomb, in red sandstone with white marble, and it is the model for the Taj. The Taj and Itimad-ud-Daulah are white-marble buildings, and the Taj, the tempting answer, comes several decades later; Bibi ka Maqbara is a still later, smaller echo of the Taj.Lutyens’s Viceroy’s House in New Delhi combines a classical composition with a central dome recalling the Buddhist stupa, deep chhajjas, jalis and a column capital hung with bells. Which description fits it best?
Show answer
Answer: D — A classical building adapted with Indian features, the “Delhi Order”
Lutyens kept a classical order and composition and added Indian elements: a stupa-like dome, chhajjas, jalis and bells on the capital. It is not the Indo-Saracenic of earlier colonial buildings, which put Mughal and Gothic motifs onto a Western plan; that label is the tempting error.In Chinese timber architecture the dougong is
Show answer
Answer: A — a set of interlocking brackets between column and beam that spreads the roof load and carries deep eaves
The dougong is the characteristic bracket system that transfers the roof load to the columns and supports the wide, upturned eaves. The tiered gate, the straw-mat module (the Japanese tatami) and the tower (the pagoda) are different things.A brick-and-concrete campus in Ahmedabad, a national assembly in Dhaka and a research institute at La Jolla were designed by an architect who spoke of “served” and “servant” spaces. He is
Show answer
Answer: B — Louis Kahn, designer of the Indian Institute of Management at Ahmedabad
The Salk Institute, the National Assembly at Dhaka and the Indian Institute of Management at Ahmedabad are Louis Kahn’s, and “served and servant spaces” is his idea. Le Corbusier worked in Ahmedabad too, which is why he is the tempting answer, but he did not design these buildings.Low-cost brick buildings in Kerala that use rat-trap bond, filler slabs and brick jalis, such as the Centre for Development Studies in Thiruvananthapuram, are associated with
Show answer
Answer: D — Laurie Baker, the British-born architect who made Kerala his home
Rat-trap bond, filler slabs and brick jalis at minimum cost are Laurie Baker’s trademarks. Herbert Baker shares the surname but worked on imperial New Delhi; Bawa is Sri Lankan, and Correa is known for Navi Mumbai and open-to-sky planning.A Catalan architect used hanging-chain (catenary) models to find the funicular forms of arches and vaults, and covered surfaces with broken-tile mosaic. He is
Show answer
Answer: C — Antoni Gaudí, architect of Casa Milà and the Sagrada Família
Catenary models, where a hanging chain gives the pure compression form when inverted, and trencadís mosaic belong to Gaudí. Utzon’s shells come from a sphere, Niemeyer’s curves are sculptural, and Gehry’s forms are produced with digital modelling.The three circular terraces at the top of Borobudur carry perforated stupas in three concentric rings, 72 in all. If the outer ring has 32 and the inner ring has 16, the number in the middle ring is ____.
Numerical answer — type the value.
Show answer
Answer: 24
Middle ring = 72 − 32 − 16 = 24. The three rings of 32, 24 and 16 follow the diminishing circumference of the terraces; a check, 32 + 24 + 16 = 72.A Japanese tatami mat measures 0.9 m by 1.8 m. The floor area of an 8-mat room, in square metres and correct to two decimal places, is ____.
Numerical answer — type the value.
Show answer
Answer: 12.96
One mat = 0.9 × 1.8 = 1.62 m². Eight mats = 8 × 1.62 = 12.96 m². Check: 0.9 × 1.8 × 8 = 0.9 × 14.4 = 12.96 m².A Chandigarh sector is a neighbourhood of 800 m by 1200 m. Assume it is planned at a gross density of 150 persons per hectare. The population it houses is ____.
Numerical answer — type the value.
Show answer
Answer: 14400
Area = 800 × 1200 = 960,000 m² = 96 ha (1 ha = 10,000 m²). Population = 96 × 150 = 14,400. Check: 100 ha would hold 15,000, and 4 ha fewer is 600 persons fewer, giving 14,400.Which of the following are typical of Mughal architecture?
Show answer
Answer: A — A charbagh garden plan around a tomb; C — Pietra dura inlay in white marble
The charbagh and pietra dura inlay are Mughal signatures, with double domes. The gopuram belongs to Dravida temples and the curvilinear shikhara to Nagara temples.Which of the following building–architect pairs are correct?
Show answer
Answer: A — Chhatrapati Shivaji Terminus (Victoria Terminus), Mumbai: F. W. Stevens; B — Gateway of India, Mumbai: George Wittet
Stevens designed the Victoria Terminus and Wittet the Gateway of India. The Victoria Memorial is by William Emerson, and the New Delhi Secretariat is by Herbert Baker, not Laurie Baker, who worked in Kerala.Which of the following statements about Oriental architecture are correct?
Show answer
Answer: A — In Chinese timber buildings the walls do not carry the roof, which rests on a post-and-beam frame; B — The Ise shrines in Japan are rebuilt at regular intervals, traditionally every twenty years; D — The pagoda is generally traced back to the Indian stupa
The timber frame with non-load-bearing walls, the periodic rebuilding of Ise and the stupa origin of the pagoda are sound. Borobudur is a Buddhist monument in Java, built under the Shailendra dynasty; the Khmer Hindu temple-mountain built by Suryavarman II is Angkor Wat.Which of the following architect–work pairs are correct?
Show answer
Answer: B — Frank Gehry: the Guggenheim Museum, Bilbao; D — Renzo Piano with Richard Rogers: the Centre Pompidou, Paris
Gehry designed the Bilbao Guggenheim, and Piano with Rogers designed the Centre Pompidou. The Sydney Opera House is by Jørn Utzon, and the Salk Institute is by Louis Kahn, not Foster.
