Abbey of the Dunes

Ten Duinen Abbey (Abbey of the Dunes) is a ruined medieval Cistercian monastery in Koksijde, in West Flanders, Belgium, a short distance from the North Sea coast. Once among the wealthiest institutions in the County of Flanders, it now survives as foundations, wall fragments and an archaeological museum.

How did the abbey begin?

The story starts with the hermit Ligerius, who settled among the dunes near today's Koksijde in 1107. A community gathered around him, adopted the Benedictine rule and, in the twelfth century, joined the Cistercian order. Sources disagree on the exact dates of affiliation, so treat the years on information boards as approximate. Saint Robert of Bruges is named as the first abbot.

Why was it so wealthy?

Lay brothers managed large landholdings and raised sheep, supplying wool to Flanders' cloth industry. At its height the estate reached roughly 10,000 hectares, according to one source. That made the abbey an economic as well as spiritual force across the region.

What led to its decline?

There were several causes. Some accounts point to the Black Death, which left the community short of monks and lay brothers. Others mention destruction during the religious wars of the sixteenth century, when the abbey was sacked and burned. Drifting dunes eventually buried the site, and in 1627 the monks relocated to Bruges. French revolutionary authorities abolished the abbey in 1796 and expelled the monks. The Bruges buildings later became a seminary.

What can you see in Koksijde today?

The ruins are part of the municipal museum Abdijmuseum Ten Duinen 1138. Visitors can see the exposed outline of the church and monastic buildings and learn about the archaeological research. The museum presents monastic daily life, the abbey's founding and its long struggle with the encroaching sand.
