Located at the foot of the castle, the Collegiate Church, formerly Church of St. Menehould, merits careful visit.
It is a crucuform building, with a choir with cut sides, with its various parts are examples of successive forms of Gothic local art.
The stalls of the monks of the fifteenth century have been preserved and offer visitors the spectacle of grotesque sculptures that adorn the "miséricordes" (small consoles under the seat).
Other elements of wood, fencing choir that had been offered by Charles de Tranchelion and his wife Françoise de Silly in the early sixteenth century, were restored some years ago by the Museum of Decorative Arts in Paris, where they were kept.
A sign bears the initials KF corresponding to Charles de Tranchelion (K) and Françoise de Silly (F).
