A little history
The first lord of Groslay was Odon or Éudes de Groslay at the end of the 11th century. In the 13th century, the village became a fief of the Montmorency family, then of the Condé in the 17th century. The commune lived essentially from vine-growing and market gardening until the beginning of the 20th century, with pear tree cultivation developing there from 1860. Groslay experienced a development comparable to that of the neighbouring village of Montmorency, with the construction of pleasure châteaux in the 18th century, bourgeois properties in the 19th century, and then suburban residential development in the 20th century, facilitated by the opening, in 1877, of the Paris - Persan-Beaumont railway line.
