The Church of St Marina was built outside the once fortified Bosiljina on the very bottom of the Marina Bay at the beginning of the 16th century and carries the name of a female saint that is rarely worshiped today, after which the place was later named Marina. The church, which is supposed to have been built on the foundations of the older medieval one, was given Baroque features in a later period. The church is single-nave, rectangular, with a semicircular apse to the east. Its approximate dimensions are 14 meters in length and 7 meters in width, and it is positioned in the east-west direction. In the 18th century, the church also had an external baptistery, and medieval tombstones known as stećci were dotted around the church. The church was cared for by Glagolitic priests. The work on the church and the stone altar were made by craftsman Petar Cavallieri. In the 1980s, the church of St Marina was adapted into a gallery and lost its religious function.
