Question: Does the Canal reach the ocean? Passage:Of the population of 176,125 (2002), 45% live in the capital, Palencia which is located on the Canal de Castilla. There are 191 municipalities in the province, of which more than half are villages with fewer than 200 people. The major towns in this province are: Guardo, an industrial-mining town; Aguilar de Campoo, a biscuit and tourist village in northern Palencia; Herrera de Pisuerga, a village that is the gateway to the Palencine mountain, is also known for its summer activities and Crab Festival; Venta de Banos, an important railway and industrial junction south of the province; Villamuriel de Cerrato, a village to the south of Palencia that owes its development to the Renault factory and its proximity to Palencia; Cervera de Pisuerga, in the heart of the Palencine mountains; Barruelo, a mining town that was the most populated town until the 1960s. During the Middle Ages, the Visigoths ruled Palencia. Basilica de San Juan, the oldest Visigothic church in Spain, was built in 661 in the province's Banos de Cerrato. During the thirteenth century a university was founded in the province. It was the first university in Spain and one of the first in the world. It was later shifted to Valladolid.
