Château de Jambville
Highlight • Castle
Perched on the heights of Vexin, Jambville castle is known to house the national training center for scouts and guides in France.
Each year, more than 2,000 executives participate in training. Its architecture is special since it has evolved over the centuries.
The vaulted cellars are from the 13th century, the wing from the Henri IV period and the central pavilion dates from Louis XIV.
The castle park, created in the 18th century, is a vestige of the royal forest of Arthies.
It covers 52 ha of woods and meadows and is made up of very rare tree species such as Himalayan cedar.
Also note the presence of a Greek temple built in 1775 and an old icehouse where blocks of ice taken from the frozen Seine were stored in winter. Today it is used as an oratory.
The castle can accommodate groups, associations, companies for stays, seminars during the week and at weekends. Services are also offered such as the organization of weddings or family meals.
The park is open to the public all year round.

They actually believed they had discovered the remains of a monastery.
The stripping of the dolmen delivered leather spatulas, vases, ashes and flint knives.
It was estimated in 1894 that this monument contained 150 skeletons.
It was excavated in a more scientific way in 1899 by Mr. Mortillet and restored in 1970.
The archives show the presence of roofing slabs until the 18th century.
The dolmen consists of large sandstone slabs forming the pillars.
The gaps between the pillars are filled with flat stones.
