Donjon de Vincennes: the last vestige of the royal castle could reopen to the public in 2025

Closed for several years, an exceptional medieval tower may soon welcome visitors once again. This dungeon in the Essonne region of France is the last remaining evidence of a vanished royal castle. Its future is currently in the balance, between safety work and development projects.

The Tour de Guinette, a monument steeped in history

Étampes, in southern Essonne, is home to a remarkable vestige of the Middle Ages. The Tour de Guinette is the only visible remnant of the royal castle built in the early 12th century. This fortification once served as the residence of the Capetian monarchs.

King Louis VI le Gros ordered its construction around 1130. At the time, Étampes occupied a strategic position on the road between Paris and Orléans. The castle asserted the royal power over this coveted territory.

Over the centuries, the fortress underwent numerous transformations. Successive wars and abandonment led to its gradual ruin. Only the keep stood the test of time, still dominating the town with its imposing silhouette.

“This monument bears witness to the importance of Étampes in the history of medieval France.

Unique architecture

The Tour de Guinette has a rare and fascinating architectural form. Its four-lobed plan, composed of four lobes placed side by side, sets it apart from the usual military constructions. This configuration offered considerable defensive advantages at the time.

Several dozen metres high, it dominates the urban landscape. Its thick walls and narrow openings are a reminder of its primary protective function. As a result, it attracts many curious onlookers and heritage enthusiasts every year.

• Built in the early 12th century under Louis VI
• Four-lobed plan exceptional in France
• Last vestige of the royal château of Étampes
• Closed to the public since 2018 for safety reasons
• Reopening project under study

Prolonged closure raises questions among residents

Since 2018, access to the monument has remained closed to visitors. Safety issues forced the authorities to take this difficult decision. The structure posed a risk to the public.

This situation has now lasted for several years. Étampois are expressing their attachment to this symbol of their city. Many hope to be able to climb the steps of this emblematic dungeon once again.

Technical studies were carried out to assess the condition of the building. The experts identified weakened areas requiring intervention. A complete diagnosis has now been made, enabling us to plan the next stage of the project.

Restoration work in prospect

The municipality is actively working on a rehabilitation project. The elected representatives are keen to breathe new life into this exceptional heritage. Funding is also being sought to complete this ambitious project.

Restoring such a building requires specific skills. Craftsmen specializing in old buildings will have to intervene with care. Respect for the monument’s authenticity guides every technical decision.

At the same time, plans are being made for the future development of the site. The aim is to offer an enriching experience to future visitors. The dungeon could then become a major tourist attraction for the region.

A promising future for this medieval gem

Its reopening to the public represents a major cultural challenge. This vestige provides an insight into the defensive organization of royal castles. It also offers a remarkable panorama of the town and its surroundings.

Local associations are mobilizing to support this project. They organize events to raise public awareness of this heritage. Their commitment helps maintain interest in the Tour de Guinette.

Étampes has other historical treasures nearby. The collegiate church of Notre-Dame-du-Fort and the old quarter are well worth a visit. The donjon is therefore part of a coherent and attractive heritage ensemble.

The next few months will be decisive for the monument’s future. If the necessary funding is forthcoming, work could begin rapidly. Residents are looking forward to regaining access to their emblematic tower, a silent witness to eight centuries of history.
