History and description -: This mosque, known as Lat Ki Masjid was built by Firoz Shah Tughlaq (1351-88 AD), is a unique example of Tughlaq architecture. The mosque is a combination of structures, L-shaped ablution tank and a Lat (Pillar). The mosque is built partly of red and buff sandstone and partly of rubble masonry having thick plaster. Possibly extricated from destroyed Hindu temples, the stone pillars with floral and geometrical designs engraved on them support the main arched openings of the mosque. The main prayer hall has nine bays consisting of arches supported on pillars. It has a carved qibla 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. The Lat, made of sandstone, is a part of an Ashokan pillar. A few letters in Mauryan Brahmi script can be seen at the top, while in the lower portion, names of a few individuals/pilgrims have been inscribed on a subsequent date.
