Fodor's Expert Review Basílica de Nuestra Señora del Pilar

This basilica beside the famous Cementerio de la Recoleta is where Buenos Aires' elite families hold weddings and other ceremonies. Built by the Recoleto friars in 1732, it is a national treasure for its six German baroque–style altars. The central one is overlaid with Peruvian engraved silver; another, sent by Spain's King Carlos III, contains relics. The basilica's cloisters house the Museo de los Claustros del Pilar, a small museum that displays religious artifacts as well as pictures and photographs documenting Recoleta's evolution. There are excellent views of the cemetery from upstairs windows.
