Fort Santo Angel was one of four Spanish forts in the Umatac area and the oldest still in existence. Perched on a rock on the Northwest tip of Umatac Bay, Fort Santo Angel served more as a watchtower than an armed fortification. Today only some of the walls remain. A third and smaller lookout, San Jose, was constructed closer to the water's edge on the Northern tip of Umatac as Fort Santo Angel started to deteriorate near the end of the Galleon era. By the 1850's, both forts were in ruins.
