Visit hidden Rome, the one that is found underground! Who would have thought that there were so many treasures under our feet? With an expert local guide, visit the Nymphaeum of the Annibaldi, a place that is normally inaccessible to tourists, and discover a secret side of beautiful Rome. A small, tiny jewel, discovered by chance and almost destroyed on purpose when, at the end of the 18th century, Rome - by Savoy will - should have become a modern European capital. Fortunately this magical place has survived to reach us. The tour includes private tour with guide and entrance ticket, groups of max 7 people.
