Bijai Mandal, built in 14th century, is an intriguing structure, situated close to the
Begampiri Masjid in the southern part of
Delhi. It was built by
Muhammad bin Tughlaq, the second ruler of the
Tughlaq Dynasty.
Reflecting the simplicity of style of the Tughlaqs, this oblong building has a number of rooms within it. There is an octagonal structure on top of these rooms, which is believed to have been served as a watchtower. This massive octagonal structure was built on a high platform in the Indo-Islamic architecture. It can be recognized by the octagonal shape that conforms to Islamic style and the false arches with the local influence. There is a door way at each cardinal point. This building is a part of the ancient palace. There are two big holes on the floor, which were the royal vaults or the treasury.
Bijai Mandal offers a clear view of the Begampiri Masjid and the historic and magnificent Qutab Minar.
