Arippu fort

Arippu Fort (අරිප්පු බලකොටුව; அரிப்புக் கோட்டை) was built by the Portuguese and was handed over to the Dutch in 1658. The small bastion fort is located in Arippu, which is 16 km away from Mannar Island. The fort is nearly square in shape, with two bastions.

Robert Knox, English sea captain and famous British prisoner of the Kandyan King Rajasinghe II, and his companion escaped after nineteen years of captivity and reached the Arippu Fort in 1679.

The first British Governor of Ceylon, Frederick North, constructed his official summer residence at the beach front, now known as the Doric and converted the fort into accommodation for the officers, who operated the pearl fisheries in the area. The fort building was subsequently converted to a guest house but was abandoned when the civil war spread to the area.
