Chapelle Épiscopale Saint-Nicolas, Noyon, Chapel in Noyon, France

The Chapelle Épiscopale Saint-Nicolas is a medieval chapel with paired windows and an oculus window, showing an early stage of Gothic design. The ruins were restored in 2010 and are now partially displayed within the local museum.

The chapel was completed in 1183 as part of the cathedral's third building phase. In 1895, the first sections were removed to open up the view toward the cathedral's south transept.

The chapel was part of a bishop's complex that shows how important the religious life of Noyon was during the Middle Ages. It demonstrates how different church buildings worked together as one connected religious center.

The chapel ruins stand in the open beside Noyon Cathedral's south transept, reachable on foot through the cathedral quarter; the surviving fragments are visible from outside without a ticket. Parts of the site belong to the adjoining museum, so access to the masonry itself depends on museum opening.

The removal of the early vaults created an unexpected relationship between the remaining ruins and the cathedral. This side-by-side placement shows how structural changes can reshape how we see historical buildings.
