Valenzuela, Metro Manila

Valenzuela is a highly urbanized city in the National Capital Region of the Philippines, on the island of Luzon about 14 kilometers north of Manila. It is the northernmost point of Metro Manila, bordered by Bulacan province on the north, by Caloocan and Quezon City on the east, and by Malabon and Navotas to the southwest and west, with the Tullahan River separating it from Malabon. The city began as the town of Polo, established in 1623, and the 1899 Battle of Malinta of the Philippine-American War was fought there. A 1960 split created a separate town named after the physician and Katipunan member Pio Valenzuela, the split was revoked in 1963, and the merged town kept the Valenzuela name. It joined Metro Manila in 1975 and became a highly urbanized city on 30 December 1998. Once agricultural, it is now a major industrial center.
