Panoramic view of the Grand Canal just after the entrance. An ideal place for a family walk, which is also a favorite ground for runners.

In the middle of the forest stands a magnificent and imposing oak tree; you can't see a taller tree for miles around.

The Parc de Sceaux is a palace park, today 181 hectares in size, south of Paris in the municipalities of Sceaux and Antony in the Département Hauts-de-Seine. The park was designed by André Le Nôtre for Jean-Baptiste Colbert and his eldest son. It was repeatedly threatened with disappearance. During the French Revolution, it was converted into an agricultural school. At the beginning of the 19th century, the castle (from the 15th century, expanded after 1670), which was originally central to the park, was destroyed. A manor house has been documented in Sceaux since the 15th century. In 1670, Jean-Baptiste Colbert, minister of Louis XIV, was looking for a property near Paris and not too far from Versailles. He bought the manor house, acquired additional land and had the castle, which dates from 1597, extended by an unknown architect, possibly Antoine Le Pautre. The castle chapel was painted by Charles Lebrun. Artists such as François Girardon, Jean-Baptiste Tuby and Jean-Baptiste Théodon were involved in the design. Colbert's study was decorated with 24 busts of Roman emperors, senators and noble women. The large north-south axis of the garden measured over a kilometer in length. Contemporaries admired the large cascade.

In Parc de Sceaux, the cherry blossom tradition reaches its greatest dimension in the Paris region. Here's a summary of the most important points: Two colors: The park has two specialized groves – the Bosquet Nord with white cherry blossoms and the Bosquet Sud with bright pink flowers. The Hanami Festival: Every year in April (usually mid-month), thousands of people gather for Hanami. It is the Japanese cherry blossom festival, where people picnic under the trees to celebrate the beauty and transience of nature. Cultural center: There are often Taiko drum performances, traditional dances, and workshops organized by the Japanese community. Visitor rush: As the influx has increased extremely in recent years, access to the lawns under the trees in the northern grove is now strictly regulated and often requires a reservation in April.
