Église Saint-Nicolas de Rethel, Gothic and Baroque church in Rethel, France.

Église Saint-Nicolas de Rethel is a church with four naves and a distinctive square tower rising to about 50 meters. The tower displays three classical architectural orders stacked on different levels, blending Gothic and Baroque styles.

The present church was built in the 13th and 14th centuries on ruins of a 7th-century structure. A Benedictine priory founded in 1108 depended on Saint-Remi de Reims, and its church was built in 1279. The priory was dissolved in 1740, making the church entirely parochial. It was destroyed in both World Wars and rebuilt each time; after a fire in 1940, the frozen vaults collapsed on 1 January 1941, and restoration under architect Froidevaux lasted until the square tower regained its bells in 1962.

The church keeps works tied to named artists and donors: canvases by Nicolas Wibault and four paintings by Jacques Wilbault, including a Descent from the Cross and a Saint Nicholas. A black stone recumbent effigy shows Thomas-Adolphe de Fuchsamberg, lord of Vadimont and Rubigny and intendant of the Rethélois in 1656, with his wife Marie Robillard.

The building sits on Rue Étienne Dolet in central Rethel and is easy to find and approach from the street. Access is generally available, though special opening times apply during European Heritage Days in September.

The black stone recumbent effigy of Thomas-Adolphe de Fuchsamberg and his wife Marie Robillard lies inside; he was intendant of the Rethélois in 1656 and a knight of the Order of Saint-Michel in 1661. In the crypt, two female statues and a Christ in the tomb date from the 16th and 17th centuries.
