In the XIXth century, a carillon of fifty-six bells was added him(her,it). The outside(exterior) is framed(supervised) by four Romance towers (influence of the cathedral of Toul), two in facade, two others in the angles of the transept and of the bedhead. Before Revolution, all four were topped with arrows. The apse in ambulatory and radiant(shining) chapels, spreads out its round volumes, which scan batteries(drum kits) stacked(superimposed) by abutments.
