Ruderi di Coazzo

Ruderi di Coazzo is an archaeological site in the San Basilio district featuring two rooms with vaulted ceilings built from brick and tuff stone. The walls, standing roughly 3 meters high, incorporate materials from an earlier Roman villa that was later adapted for medieval monastic use.

A Roman villa originally occupied this spot and was used partly as a burial area in antiquity. In the 13th century, monks built a monastic building that incorporated the villa's remains and older tomb monuments into its construction.

The way these structures were built shows how medieval inhabitants reused earlier Roman remains and materials from older burial sites nearby. This layering of different periods demonstrates how people adapted to available resources rather than starting from scratch.

The site is located near Rebibbia metro station and is walkable from the San Basilio neighborhood. The remains stand close to Via Bernardini and Via Nomentana, making them accessible for exploration on foot.

In 1428, the Frangipane family transferred half the property to Saint Peter's Basilica, which later leased it out. This connection to one of Rome's most important structures reveals how this location played a role in the wider city's economy.
