Kalusarai Masjid is located 500 m (1,640.4 ft) to the north of the Bijaymandal but it is in a highly dilapidated state needing urgent attention for restoration in view of its heritage monument status. At present, it is occupied as a residential complex by a few families.
The Masjid was built by the famous builder of Mosques Khan-i-Jahan Maqbul Tilangani, Prime Minister during Feroz Shah Tughlaq’s reign, as one of his seven mosques; built in the same architectural style as the other six built by him. But even now the visible decorations of the mihrab appear to be more intricate than in his other mosques.
When built with rubble masonry and plastered, the mosque had seven arched openings as the frontage, three bays depth wise and crowned by a sequence of low domes in typical Toghluqi architectural style.
