Despite being rebuilt several times and featuring a completely restored interior, the church still mainly boasts the Flamboyant style (15C-16C). The magnificent west front is decorated with a profusion of delicate carvings. Inside, the beauty and simplicity of the architecture are worth admiring. The nave is 13m/42ft wide, 24m/78ft high and 96m/314ft long. The two storeys are separated by a frieze and a balustrade. Do not miss the Treasury, once the abbot's private chapel, and note the murals decorating the 16C walls.
