Gravity dam

Migratory birds feast on small species of fish as they seek refuge at the Prinza dam, a gravity dam (450 meters) on the Zapote River that serves as footbridge on the border between Barangay San Nicolas I in Bacoor City, Cavite and Barangay Talon Dos in Las Piñas City.  The dam was built by the Spaniards on April 24, 1885.
