Saint-Ouen-l'Aumône

Saint-Ouen-l'Aumône is a suburban commune in Val-d'Oise that spreads along the left bank of the Oise River. The settlement mixes housing areas with open spaces, creating a landscape where residential neighborhoods meet industrial and commercial zones.

The settlement grew from a crossing point on a Roman road near the church. Over centuries, it developed into a strategic location for trade and troop movements heading toward Normandy.

The thirteenth-century Maubuisson Abbey stands as a central architectural element, representing the medieval religious heritage of the Val-d'Oise department.

The commune is well connected by public transport, particularly the RER C line and regional trains. Schools and shops are scattered across the area, so it helps to explore different neighborhoods to find what you need.

The area contains several business parks that together host hundreds of companies. These working zones give the place a distinctly industrial character that contrasts with its residential streets.
