Located in the Rambouillet forest in the Yvelines, the Rompu pond is a very charming little body of water. As the seasons go by, the reflections in the water constitute veritable open-air frescoes. No traditional museum but a reward for adventurous hikers!

Notre-Dame du Chêne Chapel

Highlight • Religious Site

In the 16th century, on the road which links Les Mesnuls to Montfort l´Amaury, an oak tree rises, the trunk of which houses an image of the Virgin Mary, highly venerated in the region. In 1646 an oratory was erected there.
This chapel is erected on an important place of pilgrimage, frequented in particular by Queen Marie-Antoinette. The current building replaces the first chapel destroyed during the Revolution.

July 6, 2026, Château des Mesnuls

The Château des Mesnuls is a historic castle in the Louis XIII style built of brick and stone, located in the commune of Les Mesnuls, in the Yvelines department in France. The structure, protected since 1945 and officially classified as a historic monument in 1975, is not open to the public for classic individual tourist visits. The building is indeed owned by the Châteauform' chain and is entirely dedicated to corporate seminars, conferences, and private events.

Built at the end of the 12th century by the Counts of Montfort and listed as a Historic Monument since 1889, the Houdan Tower was used to watch for enemies and defend the territory. The Keep consists of a 15 m diameter and 21 m high tower, flanked by four turrets of the same height located at the four cardinal points. From the 16th century until the French Revolution, the Keep served as a prison, and executions took place at the foot of the Tower. The first water reservoir was installed in the tower in 1880. The second, built in 1952, is still visible. Tours are available on certain days.

Church of Saint Peter and Saint Paul The construction of the church is said to have been initiated by Don Roger, abbot of the very powerful Benedictine abbey of Coulombs from 1115 to 1174. At that time, the abbey stood near Nogent-le-Roi, a former fortified town located twelve kilometers away on the banks of the Eure. Spread over more than 80 parishes, it had a considerable influence in the region until the Revolution, whether from a religious, economic or social point of view. The Romanesque style that it had adopted since its original construction was reworked in the 16th century by the opening of tall Gothic windows around the choir. Finally, in the following century, during the Wars of Religion, the church suffered serious damage. When peace returned, the entrance porch was finally rebuilt in the elegant Renaissance style. In 1950, a fire destroyed the church and all its furniture; it was restored at the end of the 20th century.

Many houses of worship in France bear the title “Notre-Dame” (in German “Our Lady”) and are therefore dedicated to the Blessed Mother Mary. Sometimes the specific patronage is made clear by an additional name, such as “Assumption of Mary” or “Immaculate Conception”. Here in Les Mesnuls, the church or chapel bears the suffix "Notre-Dame du Chêne", i.e. "to the oak". This means that it is not an event in the life of the Mother of God that is referred to in the patronage, but rather a tree that gave the immediate surroundings of the church a formative shape. In fact, you can see a tree on the left and right of the building.

The Tower (commonly called "The Dungeon"), built in the 12th century under the reign of the Counts of Montfort, and classified as a Historic Monument since 1840, had the function of watching out for enemies and defending the territory. But in reality, it mainly had a dissuasive role since it was reputed to be impregnable. Built on the site of an old Merovingian necropolis, it originally consisted of an enclosure and a main tower. The enclosure, which has now disappeared, had a circular turret intended for the defense of the gate. The access door, located 4 meters from the ground then raised in the 15th century to 6 meters, was the only access to the large room on the 1st floor reserved for the military chief. It was accessed via a drawbridge.

Located at an altitude of 154 meters1, the pond covers an area of 0.8 hectares. The “Ponts-Quentin stream” flows into the Rompu pond — coming from the Holland ponds located about 1 km upstream to the east — and comes out to flow, about ten kilometers further to the west, in the Vesgre, having previously changed its name twice: first under the name of “Etang-Neuf stream” then under that of “Grapelin”. The Ponts-Quentin stream passes under departmental road 138 before flowing into the pond, which justifies the undulation of the road and its bend. The pond is part of the Rambouillet national forest, a private state domain. As such, its management is ensured by the National Forestry Office (ONF). Wikipedia
