Italy has rich collections of art, culture and literature from many periods. The country has had a broad cultural influence worldwide, also because numerous Italians emigrated to other places during the Italian diaspora. Furthermore, Italy has, overall, an estimated 100,000 monuments of any sort (museums, palaces, buildings, statues, churches, art galleries, villas, fountains, historic houses and archaeological remains), and according to some estimates the nation is home to half the world's art treasures.
