Hauz Khas Complex is a Delhi Sultanate ensemble overlooking the reservoir that supplied Alauddin Khalji’s city of Siri. The name means “royal tank.” Firuz Shah Tughlaq later cleared the silted water body and built a madrasa, mosque, his own tomb and pavilions along its banks.
The core buildings date mainly from 1352–54. An L-shaped madrasa follows two edges of the lake, pivoting around Firuz Shah’s square domed tomb. Stairs, balconies and open rooms repeatedly turn toward the water.
The surrounding village is now a dense restaurant and shopping district, but the archaeological visit is distinct. Follow the relationship between reservoir, teaching rooms, mosque and tomb; the view across water explains the plan better than any isolated façade.
Architecture
An L-shaped madrasa follows two reservoir edges. One arm extends about 76 metres and the other about 138 metres, with Firuz Shah’s tomb at their junction.
Rooms face the water on two levels. Balconies, stairs and open pavilions make the lake part of teaching and circulation.
Tughlaq architecture favours strong geometry and restrained material. Rubble masonry, plaster, quartzite and red-sandstone detail create solid volumes rather than delicate surface display.
How it was built and evolved over time
The first construction was hydraulic: a large rain-fed reservoir and inlet system serving Siri. By Firuz Shah’s reign it had silted, so channels were cleared before the banks became an architectural site.
The madrasa was set in two joined arms along the south and east edges, using the ruler’s tomb as the hinge. Multi-level rooms, projecting balconies and stairs descend toward the water, keeping teaching spaces connected to the tank.
Later urban growth reduced the reservoir and altered its inflows. Modern interventions have used storm-water diversion, treated water and constructed wetlands to keep a smaller lake functioning beside the ruins.
