Belfort Cathedral, Classical architecture cathedral in Belfort, France.

Belfort Cathedral is a Catholic cathedral in the center of Belfort, built from red sandstone quarried from the surrounding area. It has two towers and a central portico framed by columns, giving the facade a structured and orderly appearance.

Built from 1727 to 1750 as the abbey church of Saint Christopher, it was designed by Jacques Philippe Mareschal, the king's engineer in Strasbourg, and erected by contractor Henri Schuller for 146,334 livres. The south tower was only finished in 1845. It became a cathedral in 1979 with the creation of the Diocese of Belfort-Montbéliard.

The cathedral is served by the Saint-Jean-Baptiste parish, with two Sunday masses: a solemn morning mass and an evening mass for students and young professionals. A mass is also held on the first Friday of each month. The 1752 tribune organ by Jean-Baptiste Waltrin is still played; its titular organist is Jean-Charles Ablitzer, with Emmanuel Georges as co-titular.

The entrance faces the main square of the old town, making it easy to reach on foot from most of the city center. The facade was restored between 2016 and 2018, so older photos may not match what you see today.

The bells were cast in 1903 by Ferdinand Farnier and placed across the two towers so that each tower produces a different sound. Depending on where you stand in the city, you hear a different part of the chime.
