Church of Santa Maria, Deba
The Church of Santa María (a listed Spanish national monument since 1931), is considered to be one of the finest works of religious architecture in the Basque Country. Despite its size —it is more like a cathedral in size— its austere outer walls, similar in style to a limestone tower, mean that it is easily overlooked. Step inside, however, and you will be surprised by the rich interior. Not to be missed if you are visiting Deba!
