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 considered 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.
