Groslay

Groslay is a commune in the Val-d'Oise department in Île-de-France in northern France. It is located 15 km north of Paris, the capital.

Boundaries
The commune is bounded with Montmorency, Saint-Brice-sous-Forêt, Sarcelles, Deuil-la-Barre and Montmagny.

History
The name comes from Graua, a Gaulish word, that means "terrain with pebbles". The nature of the soil was particularly favorable for wine growing, which was exploited here from antiquity until the late 19th century phylloxera epidemic.

The name was first mentioned in an act of donations from the Abbey of Saint-Denis in 862. The first master of Groslay was Odon or Éudes of Groslay in the late 11th century. In the 13th century, the village became a fief of the House of Montmorency, in the 17th century of the House of Condé.

The commune was essentially about wine which was produced until the early 20th century. Groslay has seen similar developments as neighbouring Montmorency: construction of country houses in the 18th century, middle class houses in the 19th century, and garden city urbanization in the 20th century.

Groslay hasn't been subjected to large scale urbanization in the 1960s and the 1970s unlike many of its neighbours. The municipal park and the square in front of the town hall were completely renovated in 2007.

Administration
Groslay falls under the jurisdiction of the civil court of Montmorency, and the business court of Pontoise.
