and bathe in it. According to legend, Ghiyasuddin Tughlaq had commissioned the Tughlaqabad Fort at the same time the baoli was being built. Because he forbade all workers from working on the baoli, they would work on it at night. Upon discovering this, the supply of oil was restricted. The masons then lit their lamps with the water of the baoli, after a blessing. Location The neighborhood surrounding the dargah, Nizamuddin Basti, is named after the saint. The area was initially the site of the settlement of Ghiyaspur, where Nizamuddin lived, and was later named after him. The Basti's population mainly grew after refugees settled here during the Partition of India. Prior to that, the area was mainly occupied only by the pirzade, the direct descendants of Nizamuddin. The Basti area has small lodges, small eateries and shops selling elements related to Islamic culture, such as religious books, kurtas, skull caps and ittar (). It also has butcher shops. The area is divided into two parts along Mathura Road: Nizamuddin West where the Dargah complex and a lively market dominated by Muslim vendors is located, and Nizamuddin East, where the Nizamuddin Railway Station is situated. The area has been a hub for cultural activities in Delhi since the 13th century, leading to many building important buildings in close proximity to the area. This includes Humayun's Tomb and Sunder Nursery, a 16th-century heritage park. The tombs of Mirza Ghalib and Abdul Rahim Khan-I-Khana are also located in this area due to its cultural significance. The other important monuments in the Nizamuddin heritage area include Barakhamba and Lal Mahal. The dargah complex is immediately surrounded by the Sabz Burj at the intersection of Lodhi Road and Mathura Road, the Urs Mahal (a stage for the qawwalis) and the Chausath Khamba. Culture The area is referred to as the "nerve centre of Sufi culture in India". On the 17th and 18th day of the Islamic month of Rabi' al-awwal, thousands gather to observe the birth anniversary and urs (death anniversary) of the saint. Besides this, thousands also visit on the birth and death anniversaries of Amir Khusrau, Nizamuddin's disciple. Hundreds visit the dargah everyday throughout the year to pray and pay their respects. The dargah has a tradition of qawwali, especially the one on every Thursday night attracting about 1500 visitors. The regular qawwalis occur every evening after the Maghrib prayer. The dargah
