The ancient mosque built by Firoz Shah Tughlaq (1351-88 A.D.) stands out to be a beautiful example of Tughlaq architecture. Its uniqueness can be attributed with its L-shaped ablution tank and a Lat (pillar). The mosque is built partly of different sandstones and rubble masonry having thick plaster. As you enter the main prayer hall you can see nine bays consisting of arches supported on pillars. It has a carved 'qibla' (tower facing Mecca) and a pulpit in the western wall. Within the courtyard in the north-east, there is a Lat (pillar) and the mosque is named after it. A few letters in 'Mauryan Brahmi' script can be seen at the top, while in the lower portion, names of a few individuals or pilgrims have been inscribed on a subsequent date.
