What makes it unique

Its stunning stained-glass windows

Notre-Dame-en-Vaux Collegiate Church displays three historical eras of stained-glass artwork:

  • A Bay made up of Romanesque medallions in the northern chapel.
  • A set of stained-glass windows in the aisles of the nave dating from the 16th century:

A – The legend of the Battle of Clavijo which is predominantly red and gold. This masterpiece is exceptionally signed by the artist Mathieu Bléville. It depicts certain scenes from Saint Jacques’ life who appears in Matamore’s comedy with his pilgrim’s hat.

B – The glorification of the Virgin Mary where we see the donors around her.

C – The nativity, displaying barrel makers from the city.

D – The deposition of the Cross. Here, blue and white stars emerge throughout the piece.

  • Glazing was carried out during the significant restoration undertaken in the second half of the 19th century.

E – The Western Rose window, displaying the Redemption in the centre. Creating this masterpiece required an organ to be built on the sides so as not to obstruct the view and the light from the west.

A piece of history

A treasure over 1,000 years old

On the banks of

the Mau Canal


Originally located outside the city walls, Notre-Dame-en-Vaux was built on a swampy area where three rivers converged, of which only the Mau remains. It was not brought inside the city walls until the 13th century. The first chapel was built in the 9th century, the church was subsequently built and occupied by a community of canons in 1114 who lived together “in college”, hence its status as a collegiate church.

The time of the French



The collegiate church suffered greatly during the French Revolution and in the decades that followed. It was even transformed into a horse arena and then into stables, and was later invaded by the coalition armies. Throughout the 19th century, the celebrated architect, Lassus, and the Champenois abbot sought to restore the medieval architecture of Notre-Dame-en-Vaux. They had a second spire reconstructed on the façade. In addition, they restored an organ and some stained-glass windows in a Gothic style. They also repaved the ground with ancient tombstones and commissioned the Châlons artist Gustave Moriamé to design the neo-Gothic high altar.
