The choir is unaisled, but has a long vaulted chamber which served as chapter house and sacristy on its north side. The choir contains the mural tomb of the Cathedral's founder, Bishop Clement. Many of the 15th century choir stalls, which have carved misericords (including one with an unusual depiction of a bat) are preserved within the choir. Further, more elaborate, canopied stalls are preserved at the west end of the nave. Dunblane has the largest surviving collection of medieval Scottish ecclesiastical woodwork after King's College Chapel, Aberdeen. Some detached fragments are displayed in the town's museum.
