Begin your tour in St Bartholomew Square on Tiber Island (Isola Tiberina), an ancient land mass in the Tiber River, which runs through the center of Rome. This picturesque island is linked by Ponte Fabricio, one of the oldest bridges in the city.
Over the centuries, a number of interesting stories have been offered concerning the island's origins. One legend has it that following the death of hated tyrant Lucius Tarquinius Superbus in 510 BC, he was thrown into the river, and as the silt built up over his body, the island was formed. Your guide will also explain the island's uses; for example, after the great plague in 293 BC, the Temple of Asclepius was built on the island in honor of the Greek god of healing.
Cross a bridge and head to nearby Basilica di San Nicola in Carcere (Church of St Nicholas in Prison), an 11th-century church that harbors some fascinating Roman excavations. Learn about the church's real claim to fame as you tour inside, and descend below ground to marvel at remnants of three ancient Roman temples that once stood on the site. Explore pathways that Roman citizens used in the 5th century BC to trod their way between the temples and to nearby markets.
Your 2-hour tour concludes on the church's ground level. Enjoy the rest of the day exploring Rome at your leisure.
