The church, under the name of the Assumption of Our Lady (feast of August 15), is a vast building built in Balesmes stone in three campaigns: the end of the twelfth century for the choir and the choir surmounted by the bell tower (contemporaries of the cathedral of Langres, with which they offer some kinship), the thirteenth century for the first two bays of the nave, and the end of the fifteenth century for the last bay with its western portal reworked, a side portillon blocked and the external spiral staircase. The church of Balesmes has been listed as a Historical Monument since July 9, 1909.
The nave is vaulted on ribbed ribs by large boudins and large double arches that fall on capitals with hammered hooks placed on lamp-ends. It is illuminated to the south by small narrow windows widely shaken. With its long single nave (extended at the end of the fifteenth century), its avant-choeur surmounted by a stocky «langrois» bell tower and its choir with flat hair, the church of Balesmes
