The town of Arcos de la Frontera gained its name by being the frontier of Spain’s 13th century battle with the Moors. It was a bulwark of Christianity after Alfonso the Wise of Castile (1252–1284) expelled the Moors. He constructed a Gothic cathedral which remains on its high ridge. This Gothic cathedral is famed for its ten bells, which tolled throughout the war with the Moors. Several Moorish banners were taken in the nearby battle of Zahara and have been on display in a church in Arcos since 1483.
Cathedral of Saint Mary of the See (Spanish: Catedral de Santa María de la Sede), better known as Seville Cathedral, is a Roman Catholic cathedral in Seville, Spain. It is the largest Gothic cathedral and the third-largest church in the world. Also its cemetery serves as the burial site of Christopher Columbus. [Ref. Wiki]
Biserica Evangelica/the Evangelical Cathedral: This impressive structure, featuring five pointed towers, was built in 1520 on the site of an old Roman basilica. The simple, stark interior is in total contrast to that of the Catholic Church.
