The Alamgir Mosque, Varanasi, also known as Beni Madhav ka Darera and Aurangzeb's Mosque. It is a mosque built in the 17th century by emperor Aurangzeb over the ruins of a Hindu temple in Varanasi.
The mosque is located at a prominent site above the Panchganga Ghat of the Ganges. Emperor Aurangzeb had captured Banaras and built a mosque and named it as Alamagir Mosque in the name of his own honorific title "Alamgir", which he had adopted after becoming the emperor of the Mughal empire.
The mosque built over the ruins of a Hindu temple is architecturally a blend of Islamic and Hindu architecture, particularly as the lower part of the walls of the mosque were built entirely from the remains of the Hindu temple. The mosque has high domes and minarets. Two of its minarets were damaged; one minaret collapsed killing a few people and the other was officially brought down owing to stability concerns. The Panchaganga Ghat where five streams are said to join.
