Arthous Abbey (formerly known as the Abbey of St. Mary of Arthous) was founded in 1167 in a deserted area bordering the Basque Country. The abbey belongs to the Order of Premonsterians.
The abbey was badly damaged due to religious wars in the 16th century. In particular, the Huguenots burned the choir of the church and canonical buildings in 1571, and the archives were eradicated.
The abbey church was built in a late Romanesque style and its monastery buildings reconstructed in the 17th and 18th centuries. They are an interesting example of modern canonical architecture. The abbey ceased to exist completely in 1791 and was used as a farm. A dilapidated church served as a barn. Almost nothing remained of the original monastic buildings except for the foundations of the western and northern walls.
In 2021, the Arthous Abbey is celebrating its origins and its collections which gave birth to the museum. The exceptional sculptures of prehistoric horses discovered in the 1960s in the neighboring town of Sorde-l'Abbaye, of which it is the custodian, are the subject of a photographic exhibition and a new space for promotion: the treasure room.
References:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
