Lyon.

Saint-Jean Cathedral anchors historic Vieux Lyon with a Gothic façade, layered medieval fabric and a celebrated astronomical clock inside the nave.

The cathedral gives the old town a clear historical center. Its construction spans centuries, so the exterior and interior show changing architectural ideas rather than one uniform style. The astronomical clock adds a precise work of mechanics, while the forecourt opens a direct view toward Fourvière.
