Forum of Centum Prata

Centum Prata was a Roman settlement located in the modern-day municipality of Rapperswil-Jona in Switzerland. The site is the most important site of the Gall-Roman era located in St. Gallen.

The remains of the settlement include sections of the forum where the foundations, a column and floor remains standing among the modern houses. Another building also remains within the forum. Located in the graveyard is a small section of foundation from a Roman bathhouse.

The forum is also speculated to have been used as a temple due to its central location and the front pillars.
