Abbaye du Betton, abbey located in Savoie, in France

The Abbaye du Betton is a Cistercian nuns' monastery founded in 1133 in the Gelon valley, in the commune of Betton-Bettonet, Savoie. Only the church ruin remains in the village; the long, low building in the photograph has a weathered grey shingled roof, pale mottled beige plaster walls, evenly spaced windows and a door, some with dark shutters or grates, and a small dormer on the roof.

The monastery was founded around 1133 and began as a priory under La Trinité before becoming an abbey by the late 12th century. After fires and war damage in the 1600s, it was partially rebuilt but lost its religious use following the French Revolution.

The abbey's name derives from Bitumen, its earliest recorded name. Noble nuns brought a dowry on entering, and the community also lived on tithes from many neighbouring parishes and on vineyards and alpine pastures donated by families such as the Miolans and Montmayeur. The Montmayeurs obtained a burial chapel dedicated to Saint John the Baptist; Gaspard de Montmayeur, who died of plague in Italy, was buried there in 1483.

The abbey stood in the Gelon valley, on the left bank, where the slopes of the Montraillant ridge meet the valley floor, in Betton-Bettonet. Only the church ruin remains in the village today; the monastery was closed and sold in 1791. The site lies roughly 20 km from Tamié Abbey, east of Chambéry.

The abbey was suppressed and sold in 1791 during the French Revolution, and from 1827 to 1858 the buildings housed a home for disabled people. Today only the church ruin remains in the village of Betton-Bettonet, in the Gelon valley below the Montraillant ridge.
