The Rafael Larco Herrera Archaeological Museum (Museo Arqueolegico Rafael Larco Herrera), founded in 1926, is the world's largest private collection of pre-Columbian art; with an astonishing array of gold, silver, semi-precious stones and textiles. The collection's predominant strength is in Mochica ceramics, from the north coast of Peru, of which the erotic ones are the most famous. Their notoriety ought not to obscure the fact that the museum presents a complete view of the cultural development of ancient Peru through a selection of its 45,000 pieces, housed in a colonial building of the 18th century.
