Église Saint-Pierre de l'Almanarre, Romanesque abbey in Hyères, France

Église Saint-Pierre de l'Almanarre is a ruined Cistercian abbey church built in Provençal Romanesque style, with a single nave originally ending in a semi-circular apse and a flat chevet. Its barrel vault has collapsed, and five door thresholds remain visible: two west, two south (likely to the cloister) and one north. Excavations in 1958–1963 uncovered a medieval tiled floor in the south nave, considered the oldest, and a 2.20 m wide street with an east sidewalk beneath the third bay.

Benedictine monks founded the abbey of Almanarre in 989 on the site of ancient Olbia, three leagues from the sea. In 1220 Cardinal Conrad, papal legate, replaced them with Cistercian nuns from Saint-Pons de Gémenos; the community was received into the Cistercian order in 1223 and placed under Le Thoronet. In 1409 pirates drove the nuns to Hyères, where they remained until the Revolution dissolved the house in 1793.

The name Almanarre probably comes from the Arabic for "lighthouse", a reminder of the site's use before the monks arrived. The abbey's church had five doorways: two west, two south toward the cloister, one north. The cemetery at its chevet held nearly 500 graves of nuns and lay workers from the 13th and 14th centuries.

The site is located near the L'Almanarre district and can be reached on foot or by car, as it is an open-air location. It is helpful to wear sturdy shoes and check for local information, as there is no large visitor center.

Beneath the third bay of the church, excavations reached the Greek level and revealed a 2.20-metre-wide street with a pavement on its east side, showing that the monastic site sits directly on the ancient settlement of Olbia. The cemetery at the church's chevet held nearly 500 graves of nuns and lay workers from the 13th and 14th centuries.
