Church of Santa María de la Asunción, Castro Urdiales

The Church of Santa María de la Asunción is a Gothic structure in Castro Urdiales built with three naves and characteristic flying buttresses and spires. The French Gothic architectural style defines the entire building and creates a distinctive appearance at the harbor.

Construction started in the early 13th century under King Alfonso VIII of Castile, during a period of economic expansion through maritime trade. The building developed during this era of growth, reflecting the rising importance of this coastal settlement.

The church displays a collection of religious artworks, including a white Virgin statue and a reclining Christ relief. These works remain visible to visitors and serve as focal points within the space.

The building stands near the harbor and is easy to reach by following the coastal streets. It is best to visit during daylight to see the architectural details clearly.

The structure suffers from a natural deterioration process where the stone gradually transforms into sandy material, a phenomenon requiring specialized conservation measures. This process often goes unnoticed by visitors but shapes the ongoing restoration work at the site.
