"Cathédrale Sainte-Marie" Built between the 12th and the 16th centuries on the site of a Roman church, this gothic building which is reminiscent of the Champage region was largely restored and two spires were built in the late-19th century. The Cathedral of St Mary or Our Lady of Bayonne has been listed as UNESCO World Heritage since 1998 as part of the "Pilgrim's Route to Santiago de Compostela".
