Flône Abbey, Religious complex in Amay, Belgium

Flône Abbey stands on the left bank of the Meuse at Amay, its buildings grouped around a double courtyard centred on the church of Saint-Matthieu. The abbey's emblem, a corner tower visible from the river and the road, rises above the complex; the brewery, rebuilt in the 17th and 18th centuries, is the oldest surviving part.

Around 1075 three lay brothers from Hesbaye, Rodolphe, Félicien and Lambert, settled at Flône where the stream meets the Meuse, on land given by Bishop Henry of Verdun, and built an oratory to Saint Matthew, a mill and a shelter for travellers on the Tongres-Amay-Arlon road. In 1189 the priory became an abbey of Augustinian canons. Calvinist troops of William the Silent plundered it in 1568; the 17th-century rebuilding gave the double court and the corner tower. Suppressed in 1796, it passed to private owners and in 1921 to the Dames de l'instruction chrétienne.

The abbey church, now the parish church of Flône, is dedicated to Saint Matthew. Its apse holds two paintings by Jean Del Cour (1631–1707) showing Saint Matthew and Saint Augustine, and the church keeps a pipe organ built in 1710 by Karel Dillens. The black marble tombstones of five prelates lie in the transept.

The abbey is a working school campus: in 2019 the elementary school had over 500 pupils and the secondary level over 1000, so the grounds are busy on class days. A footbridge links the abbey to the Château Goffart, built in 1905. A December 2007 fire damaged some of the old woodwork.

The relics of Saint Denise came to Flône only in 1922. A marble tablet on the sarcophagus, said to come from the Roman catacombs, reads DIONISE, V.M.I.IN.P VIX. AN. XXIX, giving her age as 29. She is invoked against headaches and bicycle or motorcycle accidents.
