A few hours from Paris, amidst ponds, tree-lined paths, and the tranquility of the Perche region, a curious structure awaits us with its stone walls pierced by windows… no roof, no floors, and almost no interior. The Château de La Ferté-Vidame, in Eure-et-Loir, is one of those places that makes an immediate impression, precisely because it is no longer quite a castle.
A ruined castle 1.5 hours from Paris
About an hour and a half from Paris, the site now draws visitors with its monumental ruins, but its history is even more spectacular. The existence of a castle here is attested as early as the 10th century. Later, the estate became the property of the Saint-Simon family: it was notably here that Louis de Rouvroy, Duke of Saint-Simon, the famous memoirist of Louis XIV’s court, stayed and wrote part of his famous Memoirs.

Nevertheless, the castle we see today is not Saint-Simon’s. In 1764, the wealthy financier Jean-Joseph de Laborde purchased the estate and decided to rebuild everything. He had the old medieval fortress razed to the ground to construct a massive classical palace designed by the architect Antoine-Mathieu Le Carpentier. The complex became enormous: nearly 150 meters of facade, a park spanning several hundred hectares, and an estate designed as one of the great landscaped estates of the 18th century.
But this splendor would not last long: the Revolution swept through, the estate changed hands, and the castle was gradually dismantled. Stones, materials, and decorative elements were salvaged, leaving only this immense stone shell open to the elements.
That is precisely what gives the place its charm today. Unlike many restored castles, La Ferté-Vidame retains an almost romantic quality. The ruins are reflected in the ponds, the park’s original vistas are still visible, and the building’s scale makes it easy to imagine the sheer grandeur of the original project.

Surrounding the ruins, the estate unfolds through its ponds, canals, expansive lawns, and forest paths that easily extend the stroll. The setting is particularly pleasant in spring and early summer, when the vegetation reclaims its place around the ruins.
The site also hides another, more unexpected story: in the 20th century, part of the estate was used by Citroën as an automotive testing center, an activity still carried out today in certain areas of the estate.
Less well-known than the grand châteaux of the Loire Valley but probably more unique, La Ferté-Vidame offers a completely different kind of getaway. Here, it is not the restored halls or royal apartments that draw visitors, but precisely what remains: an immense, unfinished, and almost unreal silhouette in the middle of the landscape.
