On the Chauburja Marg at the intersection with Ridge Road, about half a kilometer southeast of the Flagstaff Tower lies the remains of Chauburji Masjid. Built by Feroz Shah Tughlaq (1351-88), the mosque derives its name from its architectural features of having ‘four domes’, which it once had. The mosque was constructed by the sultan as a part of his palace called Kushk-i-Shikar (the hunting lodge) or Kushk-i-Jahan-Numa. However, some are of the belief that it was built as a mausoleum but the mihrab in the west wall of the western chamber confirms that it was constructed as mosque. At present the Masjid is survived by a double-storeyed structure with a large central chamber. One can also find small chambers attached to the central chamber.
