The oldest church in Troyes (12C) was significantly remodelled in the 16C. It sports a remarkable stone rood screen built in Flamboyant style, large, brightly coloured Renaissance stained-glass windows, and a fine statue of St Martha, emblematic of the 16C Troyes school. On the way out, the Flamboyant doorway to the former cemetery (1525) bears François I's salamander emblem and "F" monogram.
