Saint-Charles-Borromée Church of Sedan was a Calvinist temple at the time of its construction in 1562. With the revocation of the Edict of Nantes by Louis XIV in 1685, Protestantism was no longer recognized as a legitimate religion. The temple was transformed into a Catholic church and renamed after the cardinal Charles Borromeo. The building was modified through the addition of two towers and a clock turret between 1726 and 1837. The interior of the church distinguishes itself with its sobriety and the pure lines of its white columns. Saint-Charles-Borromée Church was classified as a Historical Monument in 1980.
