Centum Prata, Archaeological site in Kempraten, Switzerland.

Centum Prata is a Roman vicus on the eastern shore of Lake Zurich at Kempraten, in the municipality of Rapperswil-Jona. Its main road, today's Kreuzstrasse and Fluhstrasse, ran parallel to the Kempratnerbucht bay over about 300 metres north-south and 200 metres east-west. After a fire around 120 AD, stone buildings with courtyards replaced timber houses; wall remains and finds are displayed at the Römerwiese and near the forum on Meienbergstrasse.

The settlement began around 40 AD at the crossroads of major trade routes that the Romans connected between different regions. It developed into a regional center and demonstrates how Romans were economically active in this area and built their infrastructure.

The ruins reveal trade buildings, homes, and temples from the Gallo-Roman period, showing how people lived and worked here nearly 2,000 years ago. Through these remains, visitors can see how residents built their structures and what activities mattered most to the community.

The site is accessible and features information signs that explain the excavation area and describe the archaeological finds. It's best to visit on a dry day so you can clearly see the exposed structures and remains.

In 2003, before a housing development was built south of the 1894 railway embankment, excavations on about 1,500 square metres uncovered a walled Gallo-Roman temple precinct of roughly 900 square metres. Two temples with surrounding porticoes stood in its courtyard, and the larger one, built of sandstone blocks, shows heavy fire-reddening on its outer walls.
