Indulge yourself in the beautiful natural landscapes and the old-world beauty of the charming little Old Town of Tivoli, the Italian city nestling at the falls of the scenic Aniene River, by marveling at the majestic Villa Gregoriana Park, a grandiose work of hydraulic engineering preventing flooding on the Aniene River and the heavenly Villa d'Este Garden - one of the early models for wonder gardens all over Europe as well as exploring its mysterious maze of terraced cobbled alleys lined by mystic medieval buildings, such as the 13th-century Gothic House looking like something walking out of a storybook and the magnificent Rocca Pia Castle – the medieval Seat of the Bishop.
