Step back in time and visit the ruins that lie deep beneath the Palazzo Valentini, located near the whirlwind Piazza Venezia. Modern technology fills in the missing mosaics and walls in this remarkable hidden attraction, once the home of a wealthy Roman family. The whimsical Fontana delle Tartarughe (Turtle Fountain) in the Piazza Mattei is a legendary testament to love. To win the respect of the father of his beloved, a Renaissance duke had the fountain constructed overnight. Take a midnight saunter to the Michelangelo-designed Campidoglio Capitoline Hill, and just the two of you can stand at what was once the center of the Roman world.
