Other than the three Guimbal watchtowers, that looked out for Muslim slave raiders, the municipality of Miag-ao, known for its baroque church which is listed as one of four churches in the Unesco World Heritage Site, has one. Unlike the ones in Guimbal which was refurbished and beautified, this one was converted into a barangay hall in 1994.
A marble plaque placed on the wall just near the stairs:
This multi-purpose hall was originally a Spanish fortress commonly known as “kota.” It was constructed in 1760by the Spanish expeditionary forces to serve both as a watchtower and a fortress against the Muslim invaders and other colonial marauders. Renovated and improved in 1994, this “kota” now serves as a Barangay Hall of Baybay, Norte.
The watchtower is made of coral stones piled on top of each other but I’m not sure if the alleged date of 1760 is correct though. Watchtowers of this type only appeared in the 19th century.
