Why visit

Poissy is the birthplace of Guillaume Lasceux, born on 3 February 1740, organist, improviser and composer. Chef-lieu of the Pincerais under the Merovingians, it became one of the oldest royal towns of the Île-de-France, and the birthplace of Louis IX and Philip III the Bold.

Origins and history

Traces of a lake dwelling on oak piles were found when the lock of Carrières-sous-Poissy was built, and a Bronze Age sword kept in the British Museum came up during a dredging of the Seine; Gallo-Roman tombs were uncovered in 1928 under the rue de l'Église. Poissy was one of the first communes, by a charter granted in 1200 by Philip Augustus, and remained an important religious town until the Revolution, with the convents of the Dominicanesses, the Capuchins and the Ursulines. From the fifteenth century it was supplanted as a royal residence by Saint-Germain-en-Laye.
