Poissy

Poissy is a commune in the Yvelines department of the Ile-de-France region in north-central France, in the western suburbs of Paris about 23.8 kilometres from the centre of the capital. The English Wikipedia article gives about 41,000 inhabitants, who are called Pisciacais in French, making it the fifth most populated commune in Yvelines. It is one of the oldest royal cities of the region and the birthplace of Louis IX and Philip III of France, before it was supplanted from the fifteenth century by Saint-Germain-en-Laye. The Colloquy of Poissy, a Catholic and Huguenot conference, was held there in 1561. The area has long been associated with car making, from Automobiles Gregoire to Simca and Peugeot, which produced vehicles at the Poissy Plant, where the Simca Poissy engine was built from 1961 to 1991.
