Poissy is a French commune in the département des Yvelines in the Île-de-France region. Chef-lieu du Pincerais under the Merovingians, it subsequently became one of the oldest royal cities in Île-de-France, the birthplace of kings Louis IX and Philippe III le Hardi, before being supplanted from the 15th century onwards by Saint-Germain-en-Laye. It is also one of the first communes to receive a charter, granted in 1200 by Philippe Auguste, and was an important religious town until the Revolution, with the convents of the Dominicaines, the Capucins and the Ursulines.
