The Museum of Capitorio consists of three main buildings around Capitorio Square, the Old Palace, the Conservative Palace, the New Palace, and the Palace of Carvaleri-Clementino adjacent to the Conservative Palace, as well as the underground corridor connecting them. Designed by Michelangelo in 1536, the museum took more than 400 years to complete. Its earliest history can be traced back to the donation of a number of ancient bronze sculptures in 1471. Later, the collection expanded to a large number of ancient Roman statues, inscriptions, and other arts and crafts, medieval and Renaissance art, gems, coins and so on, which made people's eyes open.
