Located at the meeting point of the Ganges and Brahmaputra rivers, The Historic Mosque City of Bagerhat was founded by the general Khan Jahan in the 15th Century and was known as Khalifatabad. Extending over 50 square kilometers, the city contains some of the most significant buildings of the initial period of Muslim architecture in Bengal. The city was home to over 300 mosques, bridges, public buildings, mausoleums, water tanks composed of baked brick. The city is notable for the high concentration of finely made religious monuments, spatial planning and lack of fortifications. Designated a UNESCO World Heritage Site in 1985 the remaining monuments exhibit a unique architectural style known as Khan-e-Jahan. Khan Jahan is revered as a sufi saint today and the mosques are still active and remain a place of pilgrimage.
