Basilica San Clemente Rome

Often overlooked by the nearby Colosseum, the Basilica of San Clemente is a hidden gem that is definitely worth a visit. This three-tiered complex consists of an 11th century Basilica that was built on top of the pre-existing 4th century ”domus ecclesiae” (a secretive meeting room for early Christian worshippers) of martyr San Clemente. Go deeper under the Church and you’ll find a vault from the 3rd century AD. This Mitharic sanctuary consists of stone benches, surrounding an altar that was used during Mitharic rituals, a mystery cult of Persian origin.

Colosseum underground

Underneath the world’s largest amphitheatre lie the tunnels and chambers which hosted the mechanisms that made the spectacular battles of the Colosseum possible. The recently discovered hypogeum, from the Greek word for “underground”, is a labyrinth of rings that emulate the oval shape of the arena. Behind the scenes, a vertical winch called a capstan was pushed by slaves to elevate lions, crocodiles and bears into the arena.
