Sannois

Sannois is a commune in Val-d'Oise located northwest of Paris, covering approximately 5 square kilometers with gently rolling terrain. The town features a botanical garden and an 18th-century windmill that holds status as a protected historical monument.

The town developed gradually from a small village and expanded significantly with the growth of the Paris metropolitan area during the 20th century. This expansion transformed the formerly rural settlement into a modern residential community near the French capital.

The botanical garden here displays medicinal plants that visitors can explore in a green space within the town. The location serves people interested in traditional plant knowledge and local botanical heritage.

The town connects to Paris through Sannois railway station, which is part of the Transilien suburban rail network with frequent service. Car access is also available via several motorways that link the town to the surrounding region.

The town borders the Regional Natural Park of French Vexin, a protected area featuring forests and river landscapes. This proximity to nature offers visitors the chance to explore the region on foot or by bicycle.
