The cloister is built for canons: it is a place of prayer, meeting and relaxation. Its construction began in the 12C and it was repeatedly revamped. Three of its galleries are Romanesque, covered with a roof in Clear-Voie. They have arched arches which are based on a double row of columns surmounted by decorated capitals, the most worked of which is the pillar of the evangelists. The Galerie du Midi opens onto the neighboring hill. The northern Gothic gallery, austere style, was redone in the 15-16C. It contains the graves of seven canons, hence its name of gallery of tombs.
Other things to see here are the home today Departmental Archaeological Museum (Olivetans II) dating from the 16C and 18C. The museum was created in 1927 after the discovery in 1926 of the statues of the imperial trophy discovered fragmented in 133 pieces at the foot of the western facade of the temple of the forum dedicated to Augustus, around 13-10 BC. They are in the chapel of the olivetans which is next to the cathedral. These were inscrits to the Unesco World Heritage on Humanity listed as the “Way of Compostela in France”, The following monuments: the old Notre-Dame cathedral; The Saint-Just de Valcabrère basilica; the paleochretian basilica; and the Saint-Julien chapel.
A bit of history tell us that before the conquest of the region by the Romans, the region is the siege of the Convènes (Iberoaquitan people, different from the Gauls). Around 72 BC, the site becomes Romain, under the name of Lugdunum Convenarum for three centuries, the village has an urban center and numerous monuments: forum, temple, thermal baths, theater, trophy, market, vast villas numerous mosaics… In 410, it was acquired by the Visigoths who made Toulouse their capital, Around 430, the Paleochretian basilica was built. In 1083, Bertrand de l’Isle, grandson of Count Guillaume III Taillefer of Toulouse, is elected Bishop of Comminges He undertakes the construction of the cathedral and the cloister. From his death, on October 16, 1123, he was considered a saint in the Pyrenean region. It is canonized in 1218, Lugdunum Convenarum, then took the name of Saint-Bertrand-de-Comminges,from 1222. In 1295, Pope Boniface VIII appointed Bertrand de Got, bishop of Comminges. He became, in 1305, the first pope in Avignon, under the name of Clément V. In 1304, he launched the construction of a new Gothic church and in 1309, he himself transported the relics of Saint Bertrand. He promotes the cult of the saint, making his tomb the center of a large pilgrimage. Saint-Bertrand-de-Comminges becomes a stage of the Pyrenean Piedmont Way for the pilgrimage of Santiago de Compostela. The French revolutionaries spared the cathedral, but in 1790, the bishopric was dismantled and shared in three dioceses: Toulouse and Bayonne in France and La Seu d’Urgellin Spain, in the Val d’Aran, formerly belonging to the diocese of Saint-Bertrand de Comminges. The relics were hidden by the local people. In 1793 the Convention changed the name of Saint-Bertrand in “Hauteville”. The village which only counts around 250 inhabitants, lives mainly on tourism, especially in the upper city around the cathedral, the lower city living especially with agriculture.In 1998.
