ToggleUPSC History - Art and Culture - Indo Islamic Architecture
Indo-Islamic architecture is characterized by the Arcuate style, which revolutionized Indian construction by introducing the true arch, dome, and vault. This style replaced the indigenous Trabeate style (beam-and-lintel) and allowed for the creation of vast, column-free spaces and massive monumental structures.
1. Technical Features and Decorations
- Arcuate System: The use of the True Arch and Dome meant that the weight of the structure was distributed through the arch to the ground, rather than resting on horizontal beams.
- Double Dome: A major innovation where an inner dome provided the ceiling for the interior, while an outer, higher dome gave the building a majestic external appearance.
- Pietra Dura: A decorative technique involving the inlay of precious and semi-precious stones (like lapis lazuli, jade, and crystal) into polished white marble.
- Arabesque & Calligraphy: Since Islam prohibits human imagery in religious spaces, buildings were decorated with intricate floral patterns (Arabesque) and Quranic verses in beautiful calligraphy.
- Charbagh: A Persian garden layout divided into four symmetrical quarters by water channels, representing the “Gardens of Paradise”.
2. The Imperial Style (Delhi Sultanate)
The architecture of the Delhi Sultanate (1206–1526) evolved through five dynasties:
- Slave Dynasty: Notable for the Qutub Minar and the Quwwat-ul-Islam Mosque, which was built using materials from 27 demolished Hindu and Jain temples, showing an early blend of styles.
- Khilji Dynasty: Introduced the “true” arch and dome. The Alai Darwaza is a masterpiece of this era, featuring red sandstone and white marble.
- Tughlaq Dynasty: Known for more functional and austere architecture with sloping walls (Batter) for strength and the use of gray sandstone (e.g., Tughlaqabad Fort).
- Lodi Dynasty: Specialized in octagonal tombs and perfected the double dome technique, seen in the tombs at Lodi Gardens.
3. Regional (Provincial) Variations
Independent kingdoms developed unique architectural identities:
- Bengal School: Characterized by the use of bricks and the “Bangla Roof” (curved cornices), as seen in the Adina Mosque.
- Gujarat School: Heavily influenced by local Jain and Hindu craftsmanship, featuring fine stone carvings and delicate Jali work (e.g., Sidi Saiyyed Mosque).
- Jaunpur (Sharqi) School: Unique for its massive rectangular pylons (gateways) that dominated the facade of mosques, like the Atala Masjid.
- Deccan (Bijapur) School: Famous for the Gol Gumbaz, which features one of the largest unsupported domes in the world and a famous “whispering gallery”.
4. Mughal Architecture: The Zenith (1526–1707)
Mughal architecture moved toward extreme symmetry, luxury, and the use of marble.
- Babur & Humayun: Introduced the Charbagh garden. Humayun’s Tomb (Delhi) served as a prototype for the Taj Mahal, featuring a full double dome and high-arched alcoves.
- Akbar: Preferred red sandstone. His capital, Fatehpur Sikri, includes the Buland Darwaza and the Diwan-i-Khas, which features a unique central carved pillar supporting the emperor’s platform.
- Shah Jahan: The “Engineer King” who shifted from sandstone to white marble. The Taj Mahal represents the absolute peak of the Pietra Dura technique and architectural symmetry.
- Aurangzeb: Architecture began to decline in grandeur and decorative detail. The Bibi ka Maqbara is a notable but less grand imitation of the Taj Mahal.

Frequently Asked Questions (FAQs)
What is the 'Pietra Dura' technique?
- It is a decorative art where colored, semi-precious stones (like lapis lazuli, jade, and jasper) are inlaid into polished white marble to create intricate floral or geometric patterns. It reached its peak under Shah Jahan.
What is 'Batter' in Tughlaq architecture?
- ‘Batter’ refers to the inward sloping walls of a building. The Tughlaqs used this to provide additional structural strength and stability to their massive forts and tombs, such as Ghiyasuddin Tughlaq’s Tomb.
How does the 'True Arch' differ from the 'Corbelled Arch'?
- A Corbelled Arch is made by overlapping horizontal stone slabs until they meet at the top. A True Arch (Arcuate) uses wedge-shaped stones called ‘voussoirs’ with a central ‘keystone’ to distribute the weight outward and downward.
What is a 'Jali', and what was its purpose?
- A Jali is a perforated stone or latticed screen. It served three purposes: providing privacy for women (purdah), allowing ventilation, and creating beautiful play of light and shadow (Chiaroscuro).
Why is Fatehpur Sikri considered a "dream in red sandstone"?
- Built by Akbar, the entire city is constructed using red sandstone and represents a unique fusion of Mughal, Persian, and local Rajput/Gujarati styles, featuring structures like the Buland Darwaza and Panch Mahal.
