St Léger church is an attractive building constructed in the late Rhenish Romanesque style. The west façade, framed by two high towers, comprises a porch open on three sides. The bands of arcatures show Lombard influence. The transept, which is free of apsidioles, is crowned by an octogonal tower. Like the nave, façade and aisles, it dates from the 12C and 13C..
