Cathédrale Saint-Pierre de Rennes is a Neoclassical cathedral built between 1787 and 1845 on the foundations of a Romanesque church dating back to the 6th century. The interior is defined by a 19th-century Neo-Renaissance decorative program, featuring heavy use of marble, gold leaf, and vibrant stucco work. Its current facade, completed in 1845, stands 70 meters tall and is flanked by two towers of unequal height. The cathedral houses a significant collection of 19th-century religious art, including large-scale altar paintings and intricate woodwork. The site has served as the seat of the Archbishop of Rennes, Dol, and Saint-Malo since 1859. The current structure replaced a medieval building that suffered a partial collapse in 1490 and subsequent decay. The interior underwent a comprehensive cleaning and restoration program completed in the early 21st century. It serves as a focal point for the historic center of Rennes.
