The Essential
The easternmost of the coastal towns of Cantabria has become a holiday destination for the inhabitants of Bilbao, 35km away, which has contributed to the spread of buildings along the beach. Castro-Urdiales is laid out around the old castle, a site now occupied by a lighthouse, and the Gothic church, Iglesia Santa María de la Asunción, which is home to a painting of Christ on the Cross, attributed to Zurbarán.
