Kotwali Darwaza, Gaur

The Kotwali Gate, known locally as Kotwali Darja, is the site of the collapsed southern gateway of Gaur, the walled city that served as the capital of Bengal for 112 years. Its name comes from the word kotwal. The gate now sits on the international border between India's Malda district and Bangladesh's Chapai Nawabganj, and the spot is an official crossing point between the two countries.

The ASI dates the structure to the Delhi Sultanate, sometime between the reigns of Iltutmish (1211–1236) and Alauddin Khalji (1296–1316); the British Library suggests it may instead belong to the period after 1446, when the Bengal Sultans moved the capital back to Gaur from Pandua. The main arch, 9.15 m high and 5.10 m wide, has fallen, but smaller decorative arches survive on the city wall, which once also had semi-circular towers, battlements and openings for defence.
