Hauz Khas Complex- Delhi

Hauz Khas in Delhi is an important site that unravels a part of Emperor Ala-ud-din Khilji’s reign from his capital - Siri Fort. This site also holds forth the days of ruin that ravished the grandeur of Khilji’s reign after his death. Hauz-I-Alai is considered to be the only structure of Siri, which has survived the thwarts of ravishing time.
Hauz Khas in Delhi says that this tank was built by Ala-ud-din Khilji in 1300 to ensure continuous supply of water to Siri Fort. Initially, this tank located on the eastern side of Siri, preserved rainwater, which could be later disbursed throughout the year. With gradual passage of time, this tank dried up and Firoz Shah Tughlaq much later mended it. He also constructed various other monuments around the tank. Along with all these monuments, the site of the tank came to be known as Hauz Khas (royal tank).
If you visit this place now, you will be pleased to see that a cosmopolitan town has grown around the site, which has both residential and commercial hubs. I fact, Hauz Khas in Delhi, is now popular as a shopping center because a number of boutiques of famous fashion designers, antique and curio stores have been opened up in this area. Thus after visiting Hauz-I-Alai, you can also visit Hauz Khas Enclave, Kalkaji Temple, Lotus Temple, Nizamuddin's Shrine and Chirag Dehlvi's Dargah.

Firoz Shah Tughlaq’s tomb forms the centre of the complex, though. A liberal ruler, he is credited with a voluminous amount of architectural development during his 4-decade rule. The centre hall housing the dome is based on squinches to support the structure. Local quartzite was used for the floors & walls, giving a plaster finish for the shine.
