Built in 1814 in order to repel the invading Moors and Portuguese colonizers. These half-torn structures, 7 feet squares, 10 feet high, are vivid souls of the past. Before they were destroyed, they were twice their present height. These towers are made of black pebbles, and are gradually eroding. One tower is on top of the hill at Sitio Nipa, Culasi and the other one is at Brgy. Dumolog.
