 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 great art treasures.Italy is known for its considerable architectural achievements, such as the construction of arches, domes and similar structures during ancient Rome, the founding of the Renaissance architectural movement in the late-14th to 16th centuries, and being the homeland of Palladianism, a style of construction which inspired movements such as that of Neoclassical architecture, and influenced the designs which noblemen built their country houses all over the world, notably in the UK, Australia and the US during the late 17th to early 20th centuries.Along with pre-historic architecture, the first people in Italy to truly begin a sequence of designs were the Greeks and the Etruscans, progressing to classical Roman, then to the revival of the classical Roman era during the Renaissance and evolving into the Baroque era.
