Borca was a Portuguese fortress that stood at 12 (?) leagues from Muscat along the coast of Oman. The fortress had a triangular shape with three bastions at the corners of the triangle. In the fortress lived a Portuguese captain with 8 Portuguese soldiers and 30 lascarins.
Probably the Portuguese fort of Borca corresponds to the present city of Barka (23°46’N – 57°46’E) in Oman which is located 65 km north-west of the country’s capital Muscat.
Currently in the town of Barka there are three forts: Fort Barka, which is located a few hundred meters from the beach of the Gulf of Oman. Fort Fulaij a rectangular fort with two towers. The fortification of Beit al-Numan.
