Collegiate Church of Our Lady of Andelys, Les Andelys

The Collégiale Notre-Dame des Andelys is a magnificent Gothic church built between 1215 and 1320 on the site of an ancient abbey founded by Sainte Clotilde in 511 AD, making it one of the oldest religious sites in Normandy. The church displays a striking blend of architectural styles, from early Gothic to Flamboyant Gothic and Renaissance, visible in the contrast between its ornate south facade and classically-inspired north side. Cathedral-sized at 70 meters long with 21-meter vaults, the interior houses remarkable 16th-century stained glass windows by master glassmakers Arnoult de Nimègue and Romain Buron, as well as a rare Cavaillé-Coll organ from 1892 set within a stunning 1573 Renaissance wooden tribune.
