Dinh Cau Rock, also known as Cau Temple, is a small island, near Phu Quoc, that local fishermen pray to before embarking on fishing excursions. Located right next to the Duong Dong fishing port, it features a brightly colored lighthouse and a Buddhist shrine, making it a popular gathering place for travellers. Dinh Cau Rock was built in 1937 to commemorate Thien Hau (the goddess of the sea), who locals believe protects fishermen heading out to sea.
