Rome Pantheon & Trevi Fountain Underground Guided Tour - Vicus Caprarius Entry Included

Discover ancient Roman
architecture and history at the Pantheon

The tour begins at the Pantheon, one of the best-preserved monuments of ancient Rome. Originally built as a temple dedicated to all the Roman gods, it has stood for nearly 2,000 years. With your guide, you take a close look at its enormous dome, elegant architecture and remarkable engineering.

Head down to the underground site beneath the Trevi Fountain

Every year, countless travelers come to toss a coin into the Trevi Fountain, but few know that archaeological remains lie hidden beneath it. You enter Vicus Caprarius (the City of Water), an underground complex discovered during restoration work in 1999, and explore remains of ancient Roman buildings, an imperial-era domus and medieval structures.

See the reservoir of the Aqua Virgo aqueduct

Inside the site, you can see the castellum aquae, a large reservoir that supplied the city with water through the Aqua Virgo aqueduct. Built about 2,000 years ago, the Aqua Virgo was one of the 11 aqueducts that brought water to ancient Rome, and part of it is still in use today. Its name, meaning 'pure water', is said to come from the legend of a young maiden (virgo) who led thirsty Roman soldiers to a spring.

Seeing the remains of different eras layered on top of each other, you get a clear sense of Rome's multi-layered history.

※ The tour runs regardless of the weather.
