Chartres Cathedral

27 fascinating facts about Chartres Cathedral

1. Location: Chartres Cathedral stands at the heart of the medieval city of Chartres, about 80 kilometers southwest of Paris. It can be reached easily by train in around 1 hour from Paris Montparnasse.
2. Significance: Chartres Cathedral is one of the most important sacred buildings in France, alongside Reims, Amiens, and Notre Dame de Paris. In the Middle Ages it was one of Europe’s major pilgrimage destinations and is still regarded as one of the best preserved masterpieces of High Gothic architecture.
3. Saints Forts well shrine: Long before the first cathedrals rose on this site, there was a well more than 30 meters deep, probably of pre Christian origin, revered as one of the oldest sanctuaries in Chartres. Tradition holds that the city’s first Christians were executed here, which is why the well was considered a holy place of remembrance in the Middle Ages and its water was believed to have miraculous powers. The well became an important pilgrimage destination, but after being filled in during the 17th century it fell into obscurity and was only rediscovered around 1900. Today it can be seen in the cathedral crypt as a masonry shaft with a low parapet and is accessible during guided tours.
4. First cathedral: A bishop’s seat is documented in Chartres by the 4th century, which implies the existence of an early cathedral, even though no physical traces have survived. What is certain is that Bishop Adventus attended the Council of Cologne in 343, making him the first recorded bishop of Chartres. A bishop’s seat required a cathedral, but its exact location remains unknown.
5. Second cathedral: The so called Cathedral of Aventinus was the first securely attested church building on the hill of Chartres and was probably constructed in the early 6th century as an early Christian bishop’s church. It was dedicated to the Virgin Mary and built directly above the revered well shrine. In 743, this early cathedral was burned down by the troops of Duke Hunald of Aquitaine, marking its first clear appearance in written historical sources.
6. Third cathedral: After its destruction, a new bishop’s church was quickly built on the hill of Chartres and once again dedicated to the Virgin Mary. Its exact appearance is unknown, but it is believed to have been a larger early medieval basilica designed to strengthen the bishop’s seat and continue the site’s long religious tradition. In 858, this cathedral was completely destroyed during a Viking raid.
7. Fourth cathedral: The fourth cathedral was constructed in the mid 9th century under Bishop Gislebert and took the form of a spacious early medieval church. In 876, Charles the Bald, a grandson of Charlemagne, donated the Sancta Camisia, a Marian garment, to Chartres Cathedral, elevating it to one of the most important pilgrimage destinations of its time. In 962, the building was severely damaged by a devastating fire, while the relic itself survived unharmed.
8. Fifth cathedral: Very little is known about the period between the fire of 962 and the next major blaze in 1020. It is likely that a provisional cathedral was rebuilt during this time, primarily to allow pilgrimages to the Sancta Camisia to continue. In September 1020, this church was also destroyed by fire, although the cause remains unknown.
9. Sixth cathedral: After the catastrophic fire of 1020, Bishop Fulbert commissioned a new Romanesque cathedral whose width already came remarkably close to that of today’s Gothic structure. At its core was the Fulbert Crypt, built between 1020 and 1024, which is considered the largest crypt in France and functioned as an underground church with a Marian chapel and a focus on relic veneration. Fulbert did not live to see its completion, as he died in 1028, and the cathedral itself was finished in 1037.
10. The fire of 1194 and rebuilding: In June 1194, a devastating fire almost completely destroyed the Romanesque cathedral. The vast Fulbert Crypt and the west façade with its two towers survived and became the foundation for the new building. The Sancta Camisia, initially believed to be lost, was soon recovered intact from the crypt, which many interpreted as a sign to build an even greater and more dignified church on the same site. Construction of the Gothic cathedral began shortly afterward, its main structure was completed around 1220, and it was solemnly consecrated in 1260.
11. The coronation of Henry IV: To secure his claim to the throne, Henry IV converted from Protestantism to Catholicism in 1593. On 27 February 1594, he was crowned King of France in Chartres Cathedral, as the traditional coronation site of Reims was controlled by the Catholic League, which opposed his rule because of his Protestant faith. Four years later, with the Edict of Nantes, Henry officially recognized Protestantism and brought an end to the bloody religious wars that had shaken France for decades.
12. The fire of 1836: In June 1836, a fire destroyed the entire medieval roof structure of Chartres Cathedral after an unattended charcoal stove used during repair work ignited the wooden framework. Molten lead poured from the gargoyles and several bells melted or crashed down, yet the stone vaults protected the interior, the stained glass, and most of the building fabric from serious damage. During reconstruction, a modern metal framework was chosen instead of timber, giving the cathedral a fireproof copper roof whose distinctive patina has defined its appearance since 1841.
13. Rescue during the Second World War: Chartres Cathedral is one of the few major Gothic monuments in France to have survived both World Wars almost unharmed. Before heavy fighting began, many stained glass windows were carefully removed and stored to protect them from bomb damage. During the Second World War, an American general ordered the cathedral’s destruction, believing it to be occupied by German troops, but Colonel Welborn Griffith entered the building, confirmed it was empty, and saved it from demolition. Only hours later, Griffith was killed in combat near Chartres.
14. The unequal towers: The two towers of Chartres Cathedral dominate the west façade and differ clearly in both style and height. The southern Old Tower was built in the 12th century in the Romanesque style. After a lightning strike in 1506, the northern tower was topped with a richly decorated late Gothic spire, completed in the early 16th century.
15. The stained glass windows: Chartres Cathedral preserves the largest surviving collection of medieval stained glass in the world. More than 150 windows from the 12th and 13th centuries cover over 2,600 square meters and depict biblical scenes, saints’ legends, and scenes from everyday urban life in brilliant colors. The most famous is the Notre Dame de la Belle Verrière window, renowned for its deep Chartres Blue, created using cobalt based glass recipes whose exact composition has never been fully reconstructed. Many of the windows were donated by local craft guilds.
16. The rose windows: Chartres Cathedral features three monumental rose windows from the 13th century, regarded as masterpieces of Gothic stained glass and among the most impressive visual expressions of salvation history. The west rose depicts the Last Judgment, the north rose links Old Testament kings and prophets with the glorification of Mary, and the south rose shows Christ in glory surrounded by the 24 Elders of the Apocalypse. Together they form a carefully conceived iconographic program whose colors change with the movement of the sun, filling the interior with an ever shifting play of light.
17. The choir screens: Created between the early 16th and early 18th centuries, the choir screens are among the most magnificent sculptural ensembles of Chartres Cathedral and encircle the entire choir like a continuous stone narrative. In around 40 richly carved scenes, they chronologically depict the lives of Mary and Jesus, combining late Gothic forms with early Renaissance elements. Extending for more than 100 meters and populated by countless finely detailed figures, the choir screens rank among the most important choir enclosures in Europe and have been extensively restored in recent years.
18. The floor labyrinth: In the nave of Chartres Cathedral lies a large labyrinth made of light and dark stone slabs. While most medieval labyrinths were destroyed during the French Revolution, the Chartres labyrinth is the largest and one of the oldest surviving examples in France. Its winding path measures about 261 meters and symbolizes the Christian journey of life with its trials, detours, and eventual arrival at the center, representing the encounter with God. In both size and design, the labyrinth also echoes the form of the cathedral’s west rose window.
19. The King’s Portal: The King’s Portal on the west façade was created in the mid 12th century and is regarded as one of the oldest Gothic sculptural ensembles in France. Above the three entrances are scenes depicting Christ as judge of the world, the Ascension, and the Nativity of Jesus. On either side stand tall figures of Old Testament kings, considered the ancestors of Christ, accompanied by prophets who complete the iconographic program.
20. Sancta Camisia: The most important relic of Chartres Cathedral is the Sancta Camisia, a precious veil from the eastern Mediterranean dating to the early imperial period and traditionally believed to have been worn by Mary. When the reliquary was opened in 1712, the object long thought to be a tunic was revealed to be finely woven silk adorned with elaborate embroidery. The veil survived several fires and the French Revolution and is now preserved only in fragments, with the largest piece displayed since 2020 in a modern case in the northern choir ambulatory.
21. Saint Lubin Crypt: The Saint Lubin Crypt is one of the oldest surviving sanctuaries in Chartres and preserves masonry remains from Gallo Roman and Carolingian times, long predating the first cathedral buildings. According to tradition, during the fire of 1194 three clerics sought refuge here with the Marian veil and survived unharmed, an event interpreted as a miracle. Today the crypt can only be visited on guided tours and, with its massive walls and narrow passages, vividly conveys the early building history of Chartres.
22. Fulbert Crypt: After the fire of 1020, Bishop Fulbert commissioned a monumental underground church that, at about 230 meters in length, is considered the largest crypt in France. Its U shaped corridors lead to several chapels, including the famous Notre Dame Sous Terre. Additional highlights include a Romanesque baptismal font, medieval frescoes, and the preserved well shrine, and the crypt can only be explored as part of a guided tour.
23. Notre Dame Sous Terre Chapel: The Notre Dame Sous Terre chapel is regarded as one of the oldest Marian pilgrimage sites in Europe and continues the tradition of a Romanesque seated Madonna whose veneration is documented as early as the 12th century. The original statue was destroyed during the French Revolution and later replaced by several reconstructions. The version visible today dates from a reconstruction carried out in the 1970s.
24. The astronomical clock: In the choir ambulatory of Chartres Cathedral stands a rare astronomical clock from 1528, whose painted copper disks display not only the time but also the phases of the moon, the position of the sun, and the zodiac. In the 2000s, the elaborately designed dial was extensively restored and fitted with a new mechanism that once again accurately tracks celestial movements. Because only a few clocks of this type from the early 16th century have survived, the Chartres example is considered one of France’s most important historic timepieces.
25. The sunlight phenomenon: At the summer solstice, a precisely calculated beam of sunlight enters Chartres Cathedral through a small opening in the Apollinaris window and strikes a brass nail set into the floor, known as the Nail of Saint John. This meridian instrument, installed in 1701, once indicated true solar noon and was used to set the cathedral’s clocks. Although later alterations to the window reduced its accuracy, the moving spot of light can still be clearly observed around 21 June.
26. Chartres en Lumières: Each year, the Chartres en Lumières festival transforms more than 20 historic sites across the city into spectacular nighttime projections, with Chartres Cathedral as its most striking focal point. From spring through winter, façades, bridges, and churches are illuminated daily with artistic animations, color, and music that bring the city’s history and culture to life. The free event attracts more than a million visitors each year and ranks among the most impressive light festivals in France.
27. UNESCO World Heritage Site: Chartres Cathedral was added to the UNESCO World Heritage List in 1979 as one of the first sites to be inscribed.
