Begun in the late 11C, the Basilique St Julien was completed in 1180, then heightened and vaulted in 1259. Take a look around to admire the magnificent chevet: its terraces are in the Auvergne Romanesque style, while its ornamentation is more Burgundian. Note the original appearance of the rib-vaulted side porches, which is due to their use as chapels in the 16C, and the elegant multi-coloured pebble flooring (16C), the sculpted capitals and the contemporary stained-glass windows.
