A little history
The history of Chatou dates back to Gallo-Roman times, but it was mainly in the Middle Ages that the town began to grow in importance. Mentioned as early as the XIᵉ century, Chatou was then a rural parish dominated by a few large noble families. Its religious heritage, such as the church of Notre-Dame de l’Assomption, still bears witness to this ancient era.
From the XVIIᵉ century onwards, Chatou became a country residence prized by the Parisian nobility and bourgeoisie, who built beautiful homes here, taking advantage of its proximity to the Seine and its verdant landscapes. The development of the railway in the XIXᵉ century further strengthened this appeal, transforming Chatou into a popular holiday resort.
But it was above all at the end of the XIXᵉ century that Chatou truly entered the history of art: the Île de Chatou (now known as the Île des Impressionnistes) became a mecca for artistic and festive life. Many Impressionist painters – Renoir, Monet, Sisley, Degas, Caillebotte – frequented the guinguettes at the Maison Fournaise, painted the banks of the Seine and took part in the cultural effervescence of the place.
In the XXᵉ century, the town continued to develop while preserving its identity between historical heritage, art of living, and nature in the city. Today, Chatou showcases this rich past through its museums, heritage tours and cultural events that pay tribute to its unique artistic history.
