Castro Urdiales – Travel guide at Wikivoyage (2024)

Castro Urdiales or 'Castro' for short is a town of 32,000 people (2018) in the Spanish province of Cantabria. It is a popular tourist destination that offers a sports harbour, a fishing harbour and two beaches.

Castro Urdiales is a modern town, although its castle and the Gothic-style parish church of Santa María de la Asunción, date from the Middle Ages. It was founded by the Romans as "Flaviobriga". Its chief industries are tourism, fishing, and the preservation of fish, especially sardines and anchovies, in oil. The Lolin and La Castreña anchovy canning factories serve as a reminder of the town's closeness to this industry and its proximity to the sea.

Although the number of people registered in the town is around 32,000, in summer the population can be double or even triple this figure. The town is popular because of its beaches and scenic harbour.

In the centre of the town, the city hall is surrounded by a square. Close to it, right by the ocean, are the lighthouse and the church.

Built under the protection of King Alfonso VIII of Castile in the 13th century (though it was finished in the 15th century), it is a basilica church with three naves. In the interior are the images of the White Virgin and the Reclining Christ, and three Gothic carvings of the Magi. It was declared a National Monument in 1931.

From Pisoraca one hundred and eighty miles".

It is an eclectic-style building, with a portico of columns and other elements of Greek taste, and with a multicolored tile frieze designed by Daniel Zuloaga.
