The church was constructed specifically to replace a neo-Gothic predecessor that was destroyed in the 1945 Allied bombing of Royan.
The elliptical plan measures 46 by 32 meters, utilizing a complex structural geometry that was considered revolutionary at the time of construction.
The reinforced concrete shell of the vault is only 10 centimeters thick at its thinnest point.
Architect Guillaume Gillet was awarded the Prix de Rome, and this project is considered his most significant contribution to 20th-century religious architecture.
The interior acoustics are specifically calibrated for organ performances, making it a regular venue for summer music festivals.
The bell tower is a free-standing structure separate from the main elliptical nave, connected by a structural bridge.
The stained glass design was heavily influenced by the 'light-as-matter' concept common in post-war French architecture.
The church has survived several ocean-side climate restoration projects due to the high salt content in the air affecting the concrete exterior.
Église Notre-Dame de Royan is a landmark of Brutalist architecture completed in 1958 following the destruction of the city during World War II. Designed by architect Guillaume Gillet and engineer Bernard Laffaille, the structure is recognized for its elliptical shape and thin-shell reinforced concrete construction. Its primary aesthetic feature is the 'honeycomb' concrete facade, which allows for light to filter through glass elements into the nave. The building stands 35 meters high and features a prominent bell tower rising 56 meters. The design intentionally lacks traditional internal columns, creating a large, unobstructed interior space. It was listed as a French Historic Monument in 1988. The organ, built by Robert Boisseau in 1964, is a central feature of the interior's acoustic and visual design. The site serves as the primary Catholic parish church for the city of Royan.

Walk around the exterior perimeter to observe how the 'honeycomb' facade changes appearance with the angle of the sun.
Look for the plaque near the entrance detailing the historical timeline of the post-war reconstruction of Royan.
Check local cultural listings for summer organ concerts, as the building's acoustics are best experienced during performances.
Trying to access the roof or the bell tower, as these areas are not open to the general public.
Maintain a quiet volume; dress modestly as it is an active house of worship.
