The Abbey of Saint-Savin-en-Lavedan was a Benedictine abbey in the commune of Saint-Savin and one of the most important religious centres in the County of Bigorre. The abbey dates at least from the 10th century, and it was built by order of Charlemagne on the site of an ancient Gallo-Roman fortress. In 841, the abbey was looted and burnt by the Normans, and previously by the Saracens.
In 945, Count Raymond I of Bigorre gave the abbey a generous endowment consisting of a territory known as the Pascal de Saint-Savin, which was made of the eight villages. The church of Saint-Jean-de-Saint-Savin became their communal church.
In 1080 the abbey was united to the Abbey of St. Victor, Marseille. In 1130 Bernard d'Arcizas and Centule II, Count of Bigorre, confronted the abbot and the inhabitants of the Val d'Azun over a burial. Queen Marguerite of Navarre (1492–1549) took refuge in the abbey from a flood. From the thirteenth century, the abbey still controlled the territory of seven villages.
From the 16th century the abbey suffered due to the destruction associated with the French Wars of Religion and relaxed its discipline, although there were attempts to restore it in the 17th century by the monks of the Congregation of St. Maur.
Only three monks remained living in the abbey in 1790. In the following year, the church and the monastic buildings were converted for the use of the parish. Part of the abbey was sold for a stone quarry and the chapter house became a stable. In 1854, a strong earthquake caused further destructions. Prosper Mérimée took charge of its restoration in 1855.
References:The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
