Saint-Pierre Church

The square of the transept is bordered by four pillars with beams of tapering colonnettes. The bases are remarkable, with exquisitely decorated claws, leaves, flowers, bunches of grapes, griffins, eagles or charming cherubs.
The vaulting radiates ogives, liernes and tiercerons around a wide circle that is not a bell hole. However, based on a drawing from 1609, it appears that there was a tower on the crossing.
Each of the crosspieces is divided into two oblong bays. The colonnettes separating them are intersected by a cornice that divides the elevation into two storeys.
In the north arm, the names of the most venerated saints have been painted underneath, with that of Marguerite de Bourgogne, Queen of Jerusalem and founder of the Hospice de Tonnerre.
High windows depicting these saints, again in Renaissance style, illuminate the crosspieces. These windows were made by the Vermonet workshop, a master glassmaker from Reims, between 1884 and 1888.
In the south arm of the transept, a gallery leads to the outside above the main portal.
