Sainte-Chapelle Restoration — From Viollet-le-Duc to Today
The 1840s restoration that saved the chapel, the 21st-century stained-glass conservation, and what's original versus restored.
Sainte-Chapelle as we see it today is the result of two major restoration campaigns: the 19th-century work of architect Eugène Viollet-le-Duc (and others) that rescued the building from post-Revolutionary neglect, and the 21st-century stained-glass conservation completed in 2015. This guide is what's original 13th-century work, what's restoration, and how to recognise the difference.
The 1840s restoration
Sainte-Chapelle had been used during the Revolution (1789-1799) as a flour warehouse and later a public archive — the worst possible use for medieval stained glass. Many panels were damaged or removed; the painted decoration was whitewashed; the spire on the roof had collapsed. By the 1830s the chapel was essentially abandoned.
Eugène Viollet-le-Duc — the architect who also rebuilt Notre-Dame's spire and Carcassonne's walls — undertook a major restoration of Sainte-Chapelle starting in 1840 and continuing through the 1850s. The painted decoration of the interior columns and ceiling was repainted following the design of surviving fragments. Missing stained-glass panels were repaired or replaced with new work following medieval cartoons. The spire on the roof was rebuilt (the current spire is 19th-century, not 13th).
What's original 13th century
Substantial parts of the 13th-century stained-glass programme survive — particularly in the upper-chapel windows. Of the 1,113 panels in the upper chapel, approximately two-thirds (around 700 panels) are original 13th-century glass; the remaining one-third are 19th-century replacements made to match. The boundary is hard to tell from below; close inspection (or the official guide) identifies original vs replaced.
The architectural structure is largely original — the load-bearing stone columns, the ribbed vault, the floor plan. Painted decoration on the columns and ceiling is 19th-century restoration following medieval colour schemes. The spire on the roof is 19th-century. The carved stone capitals at the column tops are mostly 13th-century with some 19th-century replacements where the originals were too damaged.
21st-century stained-glass conservation
From 2008 to 2015, Sainte-Chapelle underwent a major 7-year stained-glass conservation campaign — the first comprehensive treatment of the 13th-century glass since Viollet-le-Duc. Each panel was carefully removed, cleaned (medieval grime and 19th-century repair varnish were removed), repaired, and reinstalled with new lead came (the lead strips holding the glass panels together).
The conservation also added a protective outer glazing (a second outer layer of clear modern glass) to slow further deterioration from acid rain and air pollution. The 21st-century conservation restored the colour intensity that had been dimmed by centuries of accumulated grime. Visitors who saw Sainte-Chapelle before 2008 and after 2015 report a noticeable difference — the windows are now richer in colour and clearer in detail. The 1,113-panel programme has never been more readable than it is today.
Frequently asked
Is the Sainte-Chapelle stained glass original 13th century?
About two-thirds — approximately 700 of the 1,113 panels in the upper chapel are original 13th-century glass. The remaining third are 19th-century replacements made by Viollet-le-Duc to match the original cartoons.
Who restored Sainte-Chapelle in the 1840s?
Eugène Viollet-le-Duc — the architect who also restored Notre-Dame and Carcassonne — led the major restoration campaign starting in 1840. The work included repainting the column and ceiling decoration, replacing missing stained-glass panels, and rebuilding the spire on the roof.
When was the most recent restoration?
2008-2015 — a 7-year stained-glass conservation campaign treating all 1,113 panels of the upper chapel. Panels were removed, cleaned, repaired, and reinstalled with new lead came. Protective outer glazing was added. The conservation restored colour intensity dimmed by centuries of grime.
Was Sainte-Chapelle damaged in the Revolution?
Yes — used as a flour warehouse and public archive during the Revolution and the early 19th century. Stained-glass panels were damaged or removed, painted decoration was whitewashed, and the roof spire collapsed. The 1840s Viollet-le-Duc restoration rescued the building from post-Revolutionary neglect.
Are the painted walls original?
19th-century repainting following surviving medieval colour fragments. The walls and columns are decorated with gold fleurs-de-lis on blue ground, vegetal motifs, and rich red panels. The colour scheme follows what survived; the actual paint is restoration.
Has anything been damaged recently?
No major damage in the 21st century. The 2019 Notre-Dame fire (a separate building 200 metres away) did not affect Sainte-Chapelle. The 7-year conservation completed in 2015 has the building in its best condition in over a century.
