To the east of the cloister is the old 13th century chapter-house, disfigured. It is lighted by three windows and has pointed arches resting on columns with crocketed capitals.
The walls of the cloister and chapter-house bear numerous traces of the bombardments.
The first door on the right in the east gallery of the cloister leads to a crypt below the church, built at the beginning of the 12th century and about 40 feet in length. It consists of two galleries with two bays, the groined ribs of which are carried on square pillars flanked by columns with cubic foliate capitals.
This crypt is prolonged, on the east, by a polygonal apse lighted by small tierce-point windows and having pointed vaulting which was rebuilt in the 13th century on the plan of the apse of the upper church (photo below).

THE HÔTEL-DE-VILLE. Front overlooking the gardens
Leaving Saint-Léger, turn to the left and follow the Rue de la Congrégation as far as the Hôtel-de-Ville.
The Hôtel-de-Ville occupies the old Hôtel de l’Intendance, built in 1772 on the site of the old castle which belonged to the Counts of Soissons in the Middle-Ages. Struck in various places by large calibre shells, it suffered considerable damage (photo above).
