Hauz-e-Alai, presently known as Hauz Khas Complex is an ancient historical ruin including various tombs, a mosque and a water tank. The water tank was first built by Allauddin Khilji, which was specially designed to store rainwater to be used during drought or dry season to fight the water crisis. This complex was established in the early 1300’s.
There is a lake in which you can see water animals and birds swimming across the lake and making the atmosphere lively. It is a nice place to hangout with friends and family as it has lush greenery and many eating outlets, stores, cafes and restaurants within the complex. It draws many locals and foreign tourists in large number throughout the year.
