La Roche-Guyon Castle

Highlight • Castle

The castle of La Roche-Guyon impresses the adventurers passing through Vexin. It dates from the Middle Ages and since its construction, each century has left its mark.

As its name suggests, the castle leans against chalk. This creates a beautiful dialogue between the building and its environment. Is this the way art finds beauty in nature?

La Roche-Guyon Castle and Keep

Highlight • Castle

Pretty village located below the slopes of the Vexin plateau on the bank of the Seine. Its castle, property of La Rochefoucauld, dominated by a medieval keep, and the arboretum are worth a visit.

Troglodyte Church of Our Lady of the Annunciation

Highlight • Other

An atypical site, the Church is rarely open but the interior is visible thanks to the windows rarely closed due to the humidity. Note the many troglodyte sites on this side of the Seine, including a second Church after Roche Guyon.

This place is in the heart of one of the favorite regions of the Impressionists, which happens to be rich in odds - some close to 18% - and in magnificent landscapes. Especially continue towards Giverny and Vernon!

Notre-Dame Church, Vétheuil

Highlight • Religious Site

Notre-Dame Church is a Catholic parish church located in Vetheuil, in Val-d'Oise. By its size, its double side plan and its particularly rich and varied furniture, it stands out from the village churches of French Vexin, because Vétheuil was a town of some importance in the Middle Ages. By its architecture, and in particular its apse of primitive Gothic style and its two Renaissance portals, the Notre-Dame church occupies a special place among the religious architecture of religion. Its heritage value was recognized early on, and it was classified as a historic monument by the 1840 list [2]. The origins of the parish and the church are not known, but we know of a first mention of the end of the eleventh century, and remains of a Romanesque steeple from the first half of the twelfth century still remain inside the current bell tower. Towards the end of the twelfth century, the construction of a new choir was launched, and it was completed at the very beginning of the thirteenth century. The bell tower was rebuilt in the Gothic style during the same century. It is impossible to comment on the nave of this period. The western parts that we see today date exclusively from the first half of the sixteenth century, and are in the Flamboyant Gothic style. The narrowness of the vessel is controlled by the distance between the stacks of the bell tower, and may also be explained by the reuse of the foundations of the old nave. The narrowness is compensated by the addition of wide and high side aisles, and a row of chapels forming a second side aisle on each side. In 1551, the local lord called on the master mason of Italian origin Jean Grappin, who erected a sumptuous southern portal protected by a porch, then a western facade flanked by two turrets. These works evoke the Italian Renaissance, and are of exceptional quality. Unlike other religious monuments in the region, the Notre-Dame church has always benefited from the restoration and maintenance work necessary for its good conservation, and it is in good condition. Vétheuil is no longer an independent parish and no longer has a resident priest, but Sunday Masses are still celebrated in the Notre-Dame church about every other Sunday.
