A flowering of Italian architecture took place during the Renaissance. Filippo Brunelleschi contributed to architectural design with his dome for the Cathedral of Florence, a feat of engineering that had not been accomplished since antiquity. A popular achievement of Italian Renaissance architecture was St. Peter's Basilica, originally designed by Donato Bramante in the early 16th century. Also, Andrea Palladio influenced architects throughout western Europe with the villas and palaces he designed in the middle and late 16th century; the city of Vicenza, with its twenty-three buildings designed by Palladio, and twenty-four Palladian Villas of the Veneto are listed by UNESCO as part of a World Heritage Site named City of Vicenza and the Palladian Villas of the Veneto.
