Château de Tremblay-les-Villages

Château de Tremblay-les-Villages, also known as the castle of Tremblay-le-Vicomte, is a medieval fortified ruin standing at the edge of the small town of Tremblay-les-Villages in the Eure-et-Loir department, on the fringes of the Thimerais region. Rather than a postcard-perfect turreted château, this is a site where the raw earthworks and stone remnants of a border fortress are still legible on the ground — a rewarding stop for anyone interested in medieval military history.

How do you get there?

Tremblay-les-Villages sits northwest of Chartres, within easy reach of Nogent-le-Roi, Châteauneuf-en-Thymerais and Dreux. The castle remains are located right in the village, near the Place de l'Église, so once you reach the village centre you can continue on foot. Driving from Chartres is the most convenient option, taking roughly fifteen to twenty-five minutes; Dreux is another practical starting point. There is no direct rail link to the village, so public transport means checking regional bus timetables and allowing for a connection.

What will you see?

The site preserves a large motte castrale — an artificial mound that once carried the main tower — flanked by the remains of semi-circular barbicans. A massive keep stands to the north of the complex, and the whole ensemble is still ringed by ditches and earthen embankments that remain clearly readable in the landscape. In the 13th century, two additional defense towers were added to reinforce the enclosure, and their traces help visitors piece together how the fortification evolved over time.

The first castle on this spot was probably built around 1070, most likely on the initiative of King Philip I, as part of a defensive line across the Thimerais meant to guard the road between Chartres and Dreux. Its position on the border repeatedly made it a target: between roughly 1075 and 1100 it suffered during Anglo-Norman raids led by Henry I, and after the English victory at Tinchebray in 1106 brought Normandy under English control, the area became the setting for prolonged frontier warfare. Another blow followed the Battle of Agincourt in 1415, when English forces under the Duke of Suffolk seized and razed castles across the region; in 1421 Tremblay was hit again during further Hundred Years' War campaigns. The fortress met its definitive end in June 1592, when a garrison from Verneuil pillaged and burned the estate — after that it was abandoned for good and became a convenient source of building stone for local residents rather than being rebuilt.

Today the grounds are privately owned, and for several years the current heirs have opened the site to visitors on an occasional basis, mainly during the Journées du Patrimoine (European Heritage Days) in September. That is the best chance to walk through the fortification layout up close, rather than viewing it only from outside the boundary.

When should you visit?

September's Heritage Days are the standout opportunity, since access is sometimes opened up and on-site explanations are occasionally organised. Outside that window, it is worth checking current information with the local municipality, since availability depends entirely on the private owners. In terms of weather, the months from May to September make it easiest to appreciate the earthworks and ditches against a green backdrop.

Frequently asked questions

Can the castle be visited year-round? No — the site is privately owned, and regular access is mainly limited to the September Heritage Days. Access is otherwise restricted.

What actually survives from the original castle? The earthen motte, traces of the semi-circular barbicans, a massive keep to the north, two defense towers added in the 13th century, and the surrounding ditches and embankments are all still visible.

Why was the castle destroyed? The fortress repeatedly fell victim to border conflicts — Anglo-Norman raids and Hundred Years' War campaigns — with the final blow coming from a fire set by a garrison from Verneuil in 1592.

Are there other attractions nearby worth combining with a visit? Tremblay-les-Villages is close to Chartres and its famous cathedral, as well as the towns of Nogent-le-Roi and Châteauneuf-en-Thymerais, making it easy to build a longer day trip around the Thimerais region.
