Osny, commune in Val-d'Oise, France

Osny is a small town in the Val-d'Oise region near Pontoise that mixes old houses with modern buildings along quiet, tree-lined streets. The Château de Grouchy with its large park serves as a focal point, while local markets and small shops define its simple, welcoming character.

The area was settled centuries ago and grew gradually as farmhouses were established, until Osny became part of the Cergy-Pontoise development zone in the 1960s. The old church and preserved farmhouses still show remnants of its agricultural past and earlier centuries.

The town's inhabitants, known as Osnyssois and Osnyssoises, gather regularly at local festivals and seasonal celebrations throughout the year. Markets, music events, and community gatherings in the main square reflect how people here enjoy staying connected through shared traditions and simple social moments.

The town is easy to explore on foot or by bicycle, with narrow streets and local markets open on specific days. Its proximity to Pontoise and good transportation connections make it simple to visit the area and reach larger cities in the region.

A popular local story tells of a farmer who once drove cattle through the streets, long before the town became a modern suburb. This memory shows how much the place has changed over time while keeping its rural character.
