Valenzuela City - Toponymy

Toponymy

Valenzuela, in Spanish is a diminutive form of Valencia, Spain which means "little Valencia". The name Valenzuela is also the surname of Pío Valenzuela, a Tagalog physician who was one of the leaders of Katipunan. He was regarded as a member of the Katipunan triumvirate that started the Philippine Revolution against Spanish colonial authorities in 1896. He also served as the provisional chairman for the Katipunan.

Originally, Valenzuela was called Polo. The name Polo was derived from the Tagalog term pulô, which means island, even though the area was not an island. The original town of Polo was surrounded by the rivers from the north and Tullahan River on the south. Hence, the enclosed land was thought to be an island and early townsmen regarded the place as Pulô which later evolved into Polo done by hispanicization of the word.

Today, the term Polo only applies to the barangay of Polo, the birthplace of Dr. Pio Valenzuela himself, which is found in the city's first congressional district.
