The Cathedral of the Saviour in Ávila, a masterpiece of late Romanesque and Gothic architecture, stands as a testament to the rich historical tapestry of Spain. Its construction, shrouded in mystery, is believed to have begun in the 12th century, possibly on the ruins of an earlier church. Notably, the cathedral's apse forms part of the city's defensive walls, showcasing its dual role as a place of worship and a fortress. This architectural gem predates other famous Spanish Gothic cathedrals and bears a striking resemblance to the Abbey Church of St Denis in France, reflecting the cross-cultural influences of the period.
