Pontoise

Pontoise is a commune in the Val-d'Oise department and sits about 28 kilometers north of Paris on the right bank of the Oise. The urban area spreads across several hills and the river valley, with a historic core that rises above the Oise.

The settlement grew from a Roman outpost called Pontisara and expanded during the medieval period into a major market and administrative center. Over the centuries the town controlled the road links between the capital and the northern regions.

The riverside walks and gardens follow the course of the Oise and show how locals spend everyday moments near the water. These spaces continue to serve as meeting points for residents and attract walkers throughout all seasons.

The railway station offers regular train connections to Paris through RER line C and several regional lines. Visitors can reach the historic center on foot from the station in about ten minutes or use local buses.

Seven underground passages carved from limestone form a cellar network beneath the historic center that once served as storage and refuge. Today some of these tunnels are accessible during special guided tours and allow a glimpse into the hidden layer of the town.
