History
Château d’Étampes was a royal fortress in Étampes, France, developed under the Capetian kings during the twelfth century around the Tour de Guinette, its surviving donjon. An earlier castle had stood west of the collegiate church of Notre-Dame, with a palace and a motte, a raised artificial mound for a fortified residence or tower. A new stronghold overlooking the valley was created between about 1130 and 1150, and its position gave it control over the route from Paris to Orléans.
From the Early Castle to the Twelfth-Century Fortress
The earlier castle was established during the reign of Robert II of France, known as Robert the Pious, who ruled from 996 to 1031. The later fortress was built on the Guinette Plateau under Louis VII, probably around 1140 to 1150. Its central donjon was followed by a series of surrounding enclosures, particularly during the reign of Philip II Augustus at the end of the twelfth century. These additions transformed the site into a large fortified complex above the valleys of the Louette, Chalouette, and Juine.
Between 1201 and 1213, the donjon served as the forced residence or place of confinement of Ingeburge of Denmark, queen of France and wife of Philip II Augustus. The tower therefore functioned not only as a military stronghold but also as a place where the monarchy could hold a high-ranking political prisoner.
War, Occupation, and Royal Use
English forces seized Étampes and its castle on 16 January 1358, but Charles V immediately recovered them. On 15 December 1411, John the Fearless besieged the town and castle and annexed them to the Duchy of Burgundy. A proposed donation of the castle by John of Berry to his brother Philip the Bold on 28 January 1387 remains uncertain.
Château d’Étampes also entered the visual culture of the late Middle Ages. Around 1416, it was used as a model in the Très Riches Heures of the Duke of Berry, a richly illustrated Christian book of hours. Charles the Bold stayed at the castle from 19 to 31 July 1465 after the Battle of Montlhéry. Anne of Brittany stayed there in 1513, followed by Claude of France in 1516.
The fortress was drawn into the Wars of Religion, the conflicts between Catholics and Protestants that divided France during the sixteenth century. The prince of Condé seized it again on 13 December 1562, and it was not recovered until 2 January 1563. The donjon underwent another siege on 4 May 1652.
Dismantling and Municipal Preservation
In 1589, Henry IV authorized the inhabitants of Étampes to dismantle the castle and reuse its stones in new construction. The Tour de Guinette was the surviving major element of the built complex. During the French Revolution, the land containing the tower was sold as national property, meaning land confiscated and sold by the revolutionary state. The purchaser demolished the remaining buildings and used the tower as an open-air quarry.
The ruined donjon was later abandoned until the French Restoration, the period after Napoleon’s fall in 1814 and 1815 when the Bourbon monarchy returned. In 1821, Louis-Philippe, Duke of Orléans, sold what remained of the castle. The town of Étampes acquired the donjon ruins in 1859 for use as a public promenade. The Tour de Guinette was classified as a French historic monument in 1862. It is now owned by the municipality of Étampes and designated for museum use. In 2025, it was selected by a heritage-identification mission concerned with endangered built heritage.
Remains
Château d’Étampes occupied the edge of the approximately 100-metre-high Guinette Plateau, on a steep slope about 200 metres long with a 25-metre drop northwest of Étampes. It overlooked the valleys of the Louette, Chalouette, and Juine, while the Paris to Orléans route ran below through the Juine valley. The castle was arranged in three defensive enclosures that rose in tiers across the slope. The geological sequence beneath the site consists of about 30 metres of sand, 2 metres of rubble, 23 metres of blue clay, 24 metres of argillaceous limestone, 4 metres of sandstone, and 23 metres of marl.
The Central Donjon
Plan and Defenses
The Tour de Guinette stood at the centre of the castle on a raised platform. Its four-lobed, clover-like plan was an example of mid-twelfth-century defensive experimentation. Each rounded lobe measured about 7 metres in diameter, and the donjon was about 72 metres across overall. It originally rose about 36 metres, while the surviving structure is approximately 27 metres high. A well was sunk at the centre. The rounded form helped deflect projectiles and allowed defenders to cover the base of the walls from above while reducing areas that attackers could approach unseen. The plan has been compared with the fortresses of Ambleny and nearby Houdan, and the Tower of Clifford at York has been considered possibly inspired by Étampes.
Interior Arrangement
Entry was through a south-facing postern, or small secondary entrance, which led into a vestibule. From there, an attacker could fall into a defensive pit about 4 metres deep. An inclined stair built into the wall led down to it. The subterranean first chamber was 10 metres in diameter, with a well and latrines. Its walls were 5 metres thick and pierced by three arrow slits. A stair within the wall, lit by two additional arrow slits, led to the first floor.
The first floor contained a guardroom 10 metres in diameter. Each lobe had an arrow slit, and the room included latrines and access to the central well. A spiral stair then rose to the second floor, opening onto a gallery lit by three windows. The gallery preceded a ceremonial hall 12 metres in diameter. One window opened through the northwest lobe, while two windows in each of the southwest and northeast lobes illuminated alcoves. The alcoves flanked two fireplaces, and the southwest recess contained a sink. Latrines were built into the eastern wall.
The ceremonial hall had a 10-metre-high ribbed vault, a ceiling supported by projecting structural ribs, carried by four columns. Two transverse arches provided additional support above the lobes. A final spiral stair rose above the vault and beneath the roof to a raised attic. The attic contained four galleries with wooden walls. A main roof covered the building and was pierced by two chimney flues. Two round additions rose above the northern and southern lobes, while another roofed element marked the spiral stair. The roof was capped by a pepper-pot roof, a small steeply shaped roof resembling an inverted funnel.
Enclosures and Residential Buildings
Inner and First Outer Enclosures
The donjon stood within an inner square enclosure measuring approximately 54 metres on each side. Four corner towers defended the enclosure, and a gate at its southeast corner was reached by a drawbridge. A first outer courtyard surrounded this inner enclosure. It was itself enclosed by a second square wall, approximately 90 metres on each side, with four more corner towers. A second well lay west of the courtyard.
Chapel and Domestic Buildings
A chapel dedicated to Saint Lawrence was attached to the northeast side of the second enclosure. It measured 36 metres long and 18 metres wide. A residential building stood to its southwest. The associated outer courtyard contained three lodgings to the west, a gallery along the eastern enclosure wall overlooking the town, and four rooms for bread-making or storage to the northwest.
Outer Defenses
A third enclosure, approximately hexagonal, surrounded the inner complex. Its northwest wall extended for about 160 metres, its northern wall for about 180 metres, and its southeast wall for about 140 metres. A rectangular southern battery, a fortified platform for defense, measured 54 by 36 metres and was strengthened by three towers.
The outer enclosure had two drawbridge entrances. The Porte d’Étampes stood to the northeast and the Porte de Dourdan to the northwest. Each entrance was separated from the inner courtyard by another defensive gate, and the two entrances were linked by an honor courtyard. Four towers marked the corners of the outer enclosure, while a moat completed the defenses. The steep terrain made the three enclosures appear as ascending levels when viewed from the town.
Surviving Evidence
The former appearance and arrangement of the castle are also represented in contemporary imagery, including the Très Riches Heures of the Duke of Berry. The surviving built complex is the ruined Tour de Guinette, whose four-lobed plan, interior spaces, defensive arrangements, and relationship to the former enclosures preserve the principal physical evidence of the twelfth-century fortress.
