Korlai Fort Korlai Fort is located on a cliff forming the western edge of the Kundalika River and was historically known as Morro de Chaul or the Hill of Chaul. It served as a strategic gateway between the fort of Chaul and northern trade centres, guarding the Bassein-Goa maritime corridor. . The fort consists of a citadel called Fortaleza Real, twelve bastions on the northern shore, and a connecting couracas or defensive wall with 305 battlements and musketry loopholes. The citadel is accessed through three inscribed entrances, with the main approach from the west, and the fort has eleven gates, including four outer and seven inner gateways, along with three Portuguese inscriptions. Within the fort are remains of the Chapel of Nossa Senhora, a cistern, barracks, stores, a magazine, an armoury, and the ruined Captain’s House, once the residence and command centre of the fort’s highest authority, possibly occupied by Matheus Pinho. A total of 21 numbered cannons are presently found across the fort. The Portuguese captured the fort from the Nizamshahi rulers of Ahmednagar in 1594 and rebuilt it in 1646, after which it passed to the Marathas in 1740 and later to the British in 1818.
