Pantheon and Trevi Fountain Underground Group Tour

Discover two of Rome's most fascinating landmarks, where history unfolds both above and below ground.

Begin your journey 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 and continues to impress visitors with its extraordinary dome, elegant architecture, and remarkable engineering.

Then explore one of Rome's best-kept secrets beneath the Trevi Fountain. While millions of visitors gather every year to admire the famous fountain and toss a coin into its waters, few realize that an extraordinary archaeological site lies hidden below.

Step into Vicus Caprarius – the City of Water, a fascinating underground complex discovered during restoration works in 1999. Here you will uncover the remains of ancient Roman buildings, walk through an Imperial-era domus, explore medieval structures, and see the impressive castellum aquae—the monumental water reservoir that supplied the city through the Aqua Virgo aqueduct.

Built over 2,000 years ago, the Aqua Virgo is one of the eleven aqueducts that brought fresh water to Ancient Rome and is still partially in use today. According to legend, its name, meaning "pure water," comes from a young maiden (*virgo*) who guided thirsty Roman soldiers to the spring that fed the aqueduct.

The archaeological site offers a unique glimpse into Rome's layered history, revealing how different civilizations built upon one another over the centuries. It is one of the city's most remarkable underground experiences and the perfect complement to your visit to the Pantheon, allowing you to discover both the grandeur of Ancient Rome and the hidden world beneath its streets.
