Red Mosque (In Albanian: Xhamia e Kuqe) is a Cultural Monument of Albania since 1961 and one of the oldest mosques in the city of Berat. According to Ottoman explorer Evliya Çelebi (1611-1682), the mosque was built under the reign of Bayazid II. It was probably built in the 15th century and probably built shortly after the conquest of Berat by the Ottomans in 1417. The oldest written record dates from 1431/32. The original names were Mosque of the ruler and Mosque of conquest.
Located outside the citadel within the Berat Castel the Mosque was used by caravans crossing the continent, and later by the Ottoman army.
Currently this mosque is ruined. The basic dimensions were 9.9 to 9.1 meters and had a wooden roof. It was built with red bricks and limestone. The minaret is unusually on the left of entrance. The cylindrical part on its top is unique in the Islam culture. Inside, a small circular staircase gives access to the top for a 360 view of the castle and the city.
