Église Saint-Alpin, Medieval church in central Châlons-en-Champagne, France.

Église Saint-Alpin is a Gothic church built of light beige stone, constructed between the 12th and 16th centuries. Its left corner shows a steep dark roof, three tall lancet windows, and a recessed pointed-arch portal with a wooden door. A vertical stone pier with a carved crown-like top separates a large traceried window from a smaller pointed-arch window along the side.

A first church stood here in the 9th century; it was rebuilt in Gothic style in 1170, and pillars and arcades from that campaign survive. The nave and side aisles with the facade date from the mid-12th century, the Renaissance-style transept from the 15th, and the side aisles were largely enlarged in the 16th century with new bays and stained glass. The building was listed as a monument historique in 1862.

The church is dedicated to Saint Alpin, the eighth bishop of Châlons, and a dedication marks his tomb inside. Two gilded eighteenth-century figures of Saint Andrew and Saint Alpin flank the nave, and two twelfth-century medallion windows, brought here from another church, survive among the sixteenth-century glass.

The church stands in the heart of Châlons-en-Champagne, between the Notre-Dame basilica and the cathedral, and between place Foch by the town hall and place de la République. The western portal is framed by two carved figures of saints, and gargoyles run along the exterior. Look for the second organ keyboard set at the level of the choir stalls on the north side.

The organ gallery holds a buffet carved by Nicolas Dupont in 1762, taken from the Bernardine abbey of Sainte-Hoïlde du Val-d'Ornain; its central crown was added in the 19th century. The buffet was listed as a monument historique in 1973, and Dupont's instrumental part in 1978.
