Hauz Khas is probably one of the most elegantly designed structures in Delhi’s architectural history, which nestles amidst a beautiful landscape and calm quiet ambience, with immense greenery and the effervescent beauty of the lake, this is the most popular hangout for the youngsters and photographers. Built in 13th century, it is one of the oldest structures of Delhi, which is still vibrant because of the heart throbbing activities that happen in the place.

Hauz Khas was known as Hauz-e-Illahi when it was constructed by Allauddin Khilji, was further raised by Feroz Shah Tughlaq as a knowledge city and a center of excellence which also served as the city for the servants where refugee intellectuals would take shelter, while fleeing from the onslaught of the Mongols.
The entire beautiful complex of Hauz Khas consists of a madrasa, which is L shaped, three domed structure, conspicuously called as the Assembly Hall for a lack of better understanding of its use, a Mosque which is near the Assembly Hall, all of which is overlooking the Hauz-e-Illahi later, when renovated by Feroz Tughlaq was called as Hauz Khas. The Madrasa built almost 25 years after Tughlaqabad was abandoned.
A unique feature about the complex, is the madrasa has a protruding mihrab wall onto the lake where the scholars can overlook the calm waters.
A poet from the Tughlaq court writes about the madrasa “The moment I entered the blessed building..its fragrance possessed the odour of amber, hyacinths, basils, roses, tulips.” & on the food: “..pheasants,herons, fish.. heaped everywhere & students sat cross-legged on carpets brought from Shiraz & Yemen..”
Jalal Rumi was the first principal of the Madrasa, who had a knowledge of 14 sciences and all 4 Quranic recitals. With some intense academic seminars and discussions happening among the students and the learned professors under the very roof, the place had a lively environment.
Unani medicine is believed to have originated in Ancient Greece but it had been passed on to many universities in Samarkand, Tashkent and brought to India finally by the refugee scholars, who would come to the Madrasa.
A place which would be lively with debates, discussions, Feroz Tughlaq chose this particular place for his final resting in the city of Mehrauli, away from his own city of Ferozabad. The Tomb is the most intricately carved tomb built with a band around of Quranic scriptures and stucco medallions which were later decorated by Ibrahim Lodhi, the dome especially is an exquisite site to watch. The best part about the tomb structure is the courtyard which served not for defense but for a place to sit and relax, unlike his ancestors from Tughlaq kingdom was something which catches the eye of a local.
