Abbaye Saint-Eusèbe de Saignon, Benedictine abbey in Saignon, France

Abbaye Saint-Eusèbe de Saignon is a former Benedictine abbey whose surviving abbey church, built at the end of the 12th century, stands 1 km east of Saignon. Its central apse, in regularly cut tan stone, carries Lombard bands of pilasters and small arches; the flanking apsidioles lack them. Each apse has a very narrow slit window, and the main apse's axial window is framed by columns with carved capitals.

Founded in the 8th century, the abbey grew into a major religious center that by the 12th century exerted influence across multiple dioceses including Apt and Nice. This expansion marked it as one of the region's most important spiritual and economic institutions during the medieval period.

Only the abbey church survives; after serving for years as a barn, it now hosts art exhibitions. The name Saint-Eusèbe appears as Beati Eusebii in the cartulary of the church of Apt in 1004. In 1431 the deserted abbey passed as a commendation to the prince-bishops of Apt, who held it until the Revolution.

Only the abbey church survives, standing about 1 km east of Saignon outside the village, so allow a short walk or drive from the centre. The building long served as a barn and now hosts art exhibitions; check locally before setting out, as opening depends on the exhibition.

Excavations on the abbey site revealed the Palais des Fronton, a Roman palace of the 2nd and 3rd centuries, before the abbey succeeded the villa Obaga. The church that survives was long used as a barn before becoming an art exhibition space.
