The Gothic apse with flying buttresses and octagonal tower of Santa Maria de la Asuncion church in Castro Urdiales
The photograph shows an architectural detail of the church of Santa Maria de la Asuncion, a masterpiece of Cantabrian Gothic built between the 13th and 15th centuries. The image highlights the structure of the apse with its system of flying buttresses that transfer the weight of the vaults to external buttresses, an engineering solution typical of Gothic architecture. At the center rises the octagonal tower of the crossing dome, crowned by an openwork balustrade and decorative pinnacles, topped by a cross. The large ogival windows allowed light to enter the church interior. The local sandstone, with golden and reddish tones, gives warmth to the building. In the background, the green hills of Cantabria can be glimpsed under a cloudy sky typical of this region's Atlantic climate.
