Parc Henri-Sellier, park in France

Parc Henri-Sellier is a 27-hectare public green space in Le Plessis-Robinson, 5 km south of Paris, made up mainly of a wooded massif. A terrace gives a wide panoramic view towards the south-east. The park is named after the French politician Henri Sellier (1883–1943).

The estate was a seigniorial domain around 1700, when a marshal laid out the terrace overlooking the valley. After World War I, Henri Sellier's housing organization bought the property to create a public park alongside residential neighbourhoods. The park is named after Henri Sellier (1883–1943), the French politician behind that scheme.

The park bears the name of Henri Sellier (1883–1943), the French politician and senator whose housing organisation bought the estate after World War I to build garden-city housing and open the grounds to the public. The name ties the green space to the interwar garden-city movement.

The park lies about five kilometres south of Paris, in Le Plessis-Robinson. The main entrance is on the side facing the town centre; from there, paths lead through the wooded massif to the terrace, which opens onto a wide view to the south-east. The ground is dirt and gravel, with stone benches along a low wall near the lawn.

A California giant sequoia planted over 150 years ago stands in the park and ranks among the oldest known specimens of this species in France. This planting reflects how nineteenth-century collectors brought exotic trees to European estates and parks.
