Musée Archéologique

Lonely Planet review

Truly surprising Celtic, Roman and Merovingian artefacts are displayed here, including a particularly fine 1st-century AD bronze of the Celtic goddess Sequana standing on a dual-prowed boat. Upstairs, the early Gothic hall (12th and 13th centuries), with its ogival arches held aloft by two rows of columns, once served as the dormitory of a Benedictine abbey.
