Gisors Church of Saint-Gervais-Saint-Protais, Gisors

The Church of Saint-Gervais-Saint-Protais is a magnificent Gothic church in Gisors, dating from the 11th century and expanded over 400 years. Originally consecrated by Pope Calixte II in 1119, the church was rebuilt after a devastating fire in 1124 and later transformed into a cathedral-sized masterpiece under Queen Blanche de Castille's patronage. The building showcases an extraordinary evolution of architectural styles: a 12th-century Romanesque tower, 13th-century Rayonnant Gothic choir inspired by Chartres Cathedral, Flamboyant Gothic nave with double side aisles from the 15th-16th centuries, and an elegant Renaissance façade.
