The Parroquia de Santa María del Puerto is a 13th-century Gothic church located in Santoña, recognized as a National Monument since 1931. The structure is built upon the remains of an older monastery dating back to the 9th century. Its interior features a notable collection of Flemish-style altarpieces, including a primary work dedicated to the Assumption of the Virgin. The church displays late Gothic architecture, highlighted by its distinctive ribbed vaults and stone masonry. Visitors can view the tomb of the church's founder, Pedro del Puerto, integrated into the nave. The exterior facade exhibits simple, defensive features typical of the period's religious architecture in northern Spain. It remains an active parish church serving the local community of Santoña.
