It was the largest structure of its kind in the Indian subcontinent and was built during the Bengal Sultanate as a royal mosque by Sikandar Shah, who is also buried inside.The vast architecture resembles the hypostyle of the Umayyad Mosque in Damascus, a style that was used during the introduction of Islam in new areas.It was built with rubble masonry that was covered with brick, stone, coatings of stucco, plaster, concrete, glazing or lime smoothing.[7] Cut off from both north India and the Middle East in the late 8th/14th and early 9th/15th centuries, Muslim Bengali monarchs enthusiastically looked far to the west for cultural inspiration.Activists from Bharatiya Janata Party and Vishva Hindu Parishad have claimed that the mosque was built by demolishing an "Adinath Temple", and hence must be restored to the Hindus.
