Visit the art treasures of Rome
Rome has a wide range of museums, almost too many to choose from. The most famous museum is of course the Vatican Museum with the Sistine Chapel by Michelangelo. But there's much more. For example, visit the Capitoline Museum, the first public museum in the world, with a large collection of classical bronze and marble statues. Or go to Villa Borghese, where you can admire among others the great works of Bernini, Caravaggio and Canova.
