Join us for a stroll in Trastevere, the area which has the best remains of the Medieval period of Rome. Santa Maria in Trastevere, in the heart of Trastevere, arguably one of Rome's most precious Medieval relics and one of Rome's oldest churches, complete with sparkling mosaics and beautiful bell tower. See the remains of the 10th century Castle of Caetani on the Isola Tiberina where a Pope Victor III once took shelter in the 11th century from the army of Anti-pope Clemente II. Learn about Saint Cecilia, Italy's patron Saint of Music, in the basilica dedicated to her complete with ornate 9th century mosaics, 13th century tabernacle and a famous masterpiece of sculpture of the Cecilia herself. And no Roman holiday is complete without visiting the Mouth of Truth, possibly world's oldest lie-detector.
