Plaza de Espana in Seville was created for the 1929 Ibero-American Exhibition and resides in the former private grounds of a palace. The enormous Gothic Seville Cathedral replaced an Almohad mosque and contains the Giralda bell tower, originally a minaret. The Alhambra palace in Granada was converted from a 9th century castle and is renowned for its Moorish architecture, frescoes, and interior details like the Lion Court featuring 12 marble lions.
