The Casco Antiguo is the city centre district of Seville, the capital of the Spanish region of Andalusia. The Casco Antiguo comprises Seville's old town, which lies on the east bank of the Guadalquivir river. It borders the districts of Macarena to the north, Nervión and San Pablo-Santa Justa to the east, and the Distrito Sur to the south. Bridges across the Guadalquivir link the Casco Antiguo to Los Remedios, Triana and La Cartuja.
