A bend in the wall: Sevilla's ancient gate

The Puerta de Córdoba is a unique 12th-century gate in Seville's ancient city walls, constructed by the Almohads. It is one of the few gates from the fortified wall that survived into the 19th century. Its survival, and continuing interest, is due to its unique design with a bend, rare among gates from this period. While details about its history are sparse, records from the 13th century, such as the Libro del Repartimiento, do mention it, and it appears to have been unaffected by the reforms of the 16th century. In the decades that followed, it served as a chapel, an addition to a church, and a point of Evangelical interest.
