a Romanesque basilica as well as Roman ruins. There is an archeological site close to the Cathedral in which it is possible to identify the remains of a Roman thermae and of a theatre. The village itself is a medieval one, with several arches and vaults. It has several gates entering it; on the Cabirole Gate it is possible to read about the tax set by Louis XIV on fish. Another gate, the Majou Gate, is interesting in that it is the one pilgrims used. Following the ramparts it is possible to observe the Matacan Rock from which, according to the legend, Gondoald had been executed by Gunther. Former cathedral Entering the nave people will see three distinct architectural styles at the same time: the Romanesque part of the 12th century. the Gothic part of the 14th century commissioned by Bertrand de Goth. the Renaissance part as well as the organ from the sixteenth century. The narthex ends by two huge pillars with a circumference of no less than 11.45m. Over the northern and southern walls one can see the Romanesque arches, the floors are made of marble and include some tombs and sepulchres. The choir is also clearly Romanesque and offers an impressive view over the entire valley. The Gothic part is built in the Meridional Gothic style. There is a single nave that is 55m long, 16m wide and 28m tall. Over the arrow arches there are "coat of arms" from the founding bishops. The stained glasses are impressive by their level of details, almost comparable to those of Auch. The stalls within the choir were commissioned by but because of the lack of documentation it is impossible to name the artist that made them. Although and by comparison with other stalls it is often considered it was the work of Nicolas Bachelier, or rather of his school which had been using artists from France, Spain and Italy. Most of the work had been done in oak and walnut, the choir seems cut off from the rest of the church contrasting so much with the Gothic and Romanesque parts. The sixty-seven stalls represent characters from both the Old and the New Testaments, including scenes like: temptation, envy and lust. The former cathedral has been listed as a UNESCO World Heritage Site as part of the World Heritage Sites of the Routes of Santiago de Compostela in France. Population
