Sainte-Chapelle is not just a chapel. It is a gigantic reliquary turned into architecture. King Louis IX built it in the 13th century to house the Crown of Thorns of Christ, and he spent three times more on purchasing the relic itself than on building the structure. Today it is one of the most impressive Gothic monuments in Europe: almost all the walls of the upper chapel are replaced by 13th-century stained glass, which has survived to this day almost entirely.
History: A Relic Worth More Than a Palace
In 1239, Louis IX acquired the Crown of Thorns from the Latin Emperor Baldwin II for 135,000 livres — a sum equal to half the annual income of the kingdom. Two years later he purchased 22 more relics of the Passion of Christ, including a fragment of the Life-Giving Cross.
For such a treasure, a worthy setting was required. Construction began on the site of the old Chapel of St Nicholas in the royal palace on the Île de la Cité. The work was carried out from 1242 to 1248 — record-breakingly fast for that time. The presumed architect is considered to be Pierre de Montreuil. The building itself cost the treasury 40,000 livres — three times less than the Crown of Thorns itself.
The chapel was consecrated on 26 April 1248. In the eyes of medieval Europe, Paris became the "new Jerusalem" — the centre of Western Christianity.
What Sainte-Chapelle Endured
During the French Revolution, the chapel suffered greatly: the relics were plundered, the spire was broken, the stained glass was removed to a height of two metres, and the building was turned into a flour warehouse and archive. Part of the stained glass was sold or destroyed.
The restoration of Sainte-Chapelle began in 1837 under the direction of Viollet-le-Duc and other architects. The building was returned to its 13th-century appearance, and the wooden spire 33 metres high was recreated as an exact copy of the 15th-century spire.
Architecture: Walls of Light
Sainte-Chapelle is an example of Rayonnant Gothic. From the outside, the building looks rather modest, hidden in the courtyard of the Palace of Justice. Everything most impressive is inside.
The building has two levels. The lower chapel, consecrated in honour of the Virgin Mary, served as a parish church for courtiers, the guard, and servants. Its low vaults (6.6 metres) and painting in the form of a starry sky create an atmosphere more resembling a crypt.
The upper chapel of Sainte-Chapelle is what people come here for. Its vault rises to 20.6 metres. Almost the entire surface of the walls is occupied by stained glass: 15 enormous windows 15 metres high and 600 m² of coloured glass. In total, the stained glass contains 1,113 scenes from the Old and New Testaments, which must be "read" from left to right and from bottom to top.
Thin clusters of columns, almost not concealing the space, support the vaults. A contemporary of Louis IX described his impressions thus: "I was as if led into one of the most beautiful rooms of Heaven."
The Stained Glass of Sainte-Chapelle: Are They Original?
This is one of the most frequent questions from visitors. The answer is more complicated than a simple "yes" or "no."
Original glass. Approximately two-thirds of the stained glass of Sainte-Chapelle is genuine 13th-century glass. This makes them one of the most complete medieval stained-glass ensembles in the world. The glass was produced in two workshops in the forests near Paris, and the violet-manganese glass used in some details was made only in Paris.
What was lost. During the French Revolution, Sainte-Chapelle suffered greatly: part of the stained glass was removed, some was sold or destroyed. The surviving fragments are today kept in museums in Philadelphia, Cluny, and the Victoria and Albert Museum in London. In the 19th century, during the restoration by Viollet-le-Duc and other architects, about one-third of the glass and most of the lead were replaced. The stained glass suffered again in the 20th century — from air pollution and dust.
The restoration of 2008–2015. From 2008 to 2015, a large-scale restoration of seven stained-glass windows took place, timed to coincide with the 800th anniversary of the birth of Louis IX. The work was carried out using lasers: each panel was dismantled, cleaned of centuries-old layers of soot and varnish, and then reassembled.
Importantly, the restorers worked from 17th-century watercolours, which depicted the stained glass before the 19th-century restoration. Where the original painting had disappeared, it was painted anew on a separate layer of glass behind the original — this made it possible not to touch the genuine glass.
What you see now. If you are standing in the upper chapel, most of the glass you are looking at is genuine, from the 13th century. But this glass has gone through several stages of restoration, and part of the details has been restored. The lead framework connecting the pieces is to a significant extent new. And the outer protective surface of transparent glass, installed on the outside, creates an "illusion" of the original appearance when viewed from the street.
The restorers described their approach as "illusionistic" or "aesthetic," rather than "archaeological." That is, the goal was not to preserve every historical layer, but to return to the stained glass the appearance it had in the 13th century.

Tips for Visiting
• Booking: strongly recommended. Tickets with a fixed time are sold online; even with them, you must pass through security control, as at an airport, and the queue can take 30–60 minutes at peak hours.
• Best time: morning (right after opening) or late in the day. The stained glass is especially beautiful in the morning light, which illuminates the eastern windows.
• 30–45 minutes is enough to see the chapel itself, but if you want to examine the details of the stained glass, allow more.
• An audio guide is available for €4 in several languages.
• If you have time, a combined ticket with the Conciergerie gives access to the former prison where Marie Antoinette was held — it is two steps from the chapel.
• Photography is allowed without flash — this helps preserve the ancient glass.
Sainte-Chapelle is a place where architecture ceases to be merely stone and becomes light. Even if you have seen thousands of photographs, the real sensation, when sunlight passes through 600 square metres of 13th-century stained glass, turns out to be completely different. It is one of those points in Paris that is worth seeing with your own eyes.
