The High Gothic style of the Cathedral of Saint-Just and Saint-Pasteur takes its inspiration from the great cathedrals of Northern France. Its most striking feature is its unique choir, with vaulting soaring to more than 40 metres. It was built between 1272 and 1340 and remained unfinished because, in those troubled times, the Consuls refused to demolish the ramparts to provide stone to continue building. The side chapel, dedicated to Our Lady of Bethlehem, has a 14th-century altar-piece in painted stone. The Treasury, also known as the acoustic hall, displays a rich collection of liturgical objects, including ivories, gold and tapestries. Pass tickets for 15 days are available.
