Poissy (pwasi) is a commune in the Yvelines department in the Île-de-France region in north-central France. It is located in the western suburbs of Paris, 23.8 km (14.8 mi) from the centre of Paris. Inhabitants are called Pisciacais in French. With about 41,000 inhabitants, Poissy is the 5th most populated commune in Yvelines.

Poissy is one of the oldest royal cities of Île-de-France, birthplace of Louis IX of France and Philip III of France, before being supplanted from the 15th century by Saint-Germain-en-Laye. In 1561, it was the site of a fruitless Catholic–Huguenot conference, the Colloquy of Poissy.

The area was known for the early car maker Automobiles Gregoire, and since then a number of companies including Simca and Peugeot, have produced vehicles at the Poissy Plant. From 1961 until 1991 the Simca Poissy engine was made there.

Location

Poissy is located about 30 kilometres west of Paris, in the north-eastern part of the Yvelines, 8 kilometres west of Saint-Germain-en-Laye, and 23 kilometres north-west of Versailles, the departmental prefecture.

The city is limited to the east by the forest of Saint-Germain-en-Laye and to the west by the Seine.

The Hôtel de Ville was completed in 1937.[2]
