2. Basilique Notre-Dame-d’Espérance
In the last 200 years this church has seen in it all: It has been damaged in sieges and attacks in 1815, 1870, 1914, 1940 and 1945, and each time has been restored to its original designs.
The bulk of the architecture dates to 1499, save for the bell tower, which is from the 1600s.
The style is mostly Flamboyant Gothic, obvious on the extravagant southern facade with its gargoyles and pinnacles.
This decoration continues in the nave, which has remarkable keystones hanging from its vaults.
The abstract stained glass windows in the church were designed by 20th-century artist René Dürrbach.
