 
Maisons-Laffitte () is a commune in the Yvelines department in the northern Île-de-France region of France. It is a part of the affluent outer suburbs of northwestern Paris, from its centre.
Maisons-Laffitte is famous for the Château de Maisons-Laffitte, built by architect François Mansart in the 17th century, and its horse racing track, the Maisons-Laffitte Racecourse. Église Saint-Nicolas was built between 1867 and 1872.
History.
Originally called Maisons-sur-Seine (meaning "Houses upon Seine"), the commune was officially renamed Maisons-Laffitte in 1882 in honour of banker Jacques Laffitte who financed the housing developments on the estate of the Château de Maisons-Laffitte.
The Château de Maisons-Laffitte has a secret passage to what once used to be part of the Château de Maisons-Laffitte but which is now a school – Collège de l'Ermitage.
