You step off a sun-warmed cobble and descend: cool air, low vaults and a hush that makes the city above feel distant. The guide opens a gate into the Stadium of Domitian’s substructure — stone seating ribs and service corridors that once held crowds — then leads you through fissured tufa and travertine cut by centuries of water. The Vicus Caprarius beneath the Trevi Fountain appears like a city of channels, where ancient aqueduct stone still remembers the push of the Aqua Virgo.
