Aulne Abbey Ruins in Thuin

Aulne Abbey, a historical landmark in the Valley of Peace

The ancient ruins of the Aulne Abbey are located in Thuin, a sub municipality of Charleroi. The ruins are located in the Valley of Peace and belonged to the Bishopric of Liège. Nowadays, it has been registered as a historic monument by the Region of Wallonia since 2006.

We recently visited the Aulne Abbey ruins to tell you all about its history and how to reach it.

About Aulne Abbey

The former Abbey of Aulne, located near the banks of the Sambre river, in a place known as Valley of the Peace (“Vallée de la Paix”), has its origins in the 7th century and is named after the alder tree (in French “aulne”).

According to ancient records, the Abbey was originally built in 637 by a notorious thief named Landelinus, who also founded the neighboring Lobbes Abbey. The building was later transformed into a Benedictine monastery after Landelinus’ death in 656.

The Abbey was raided in 880 by the Normans, which destroyed most of the writings. The monastery was left in ruins for half a century until bishop Richarius (922-945) finally rebuilt it.

The Benedictines were replaced from the 10th century (around 974), transforming it into an Abbey with monks who lived according to strict Christian rules. At the beginning of the 13th century, when Prince-Bishop Hugo II of Pierrepont (1202-1229) was in charge, the Abbey contributed to the spiritual and material prosperity of the region.

In its further history, the Abbaye d’Aulne went through several periods of looting, wars, and disasters. Nevertheless, the Abbey acquired several beautiful and extensive lands, making it one of the most powerful abbeys in the old Netherlands. The Abbey was also known for its enormous monastic library and housed more than 50,000 books and over 4,000 manuscripts by that time.

As indicated, the Abbey endured several wars over the years; in the 15th century, it had to do with the looting of the Burgundians, while in the 16th century, it was attacked by King Henry II of France. After the revolt of the Geuzen (also in the 16th century), the Abbey was destroyed. It lasted until the beginning of the 18th century, when Abbot Carion de Thuin paid off all debts.

Abbot Carion de Thuin and his successor Barthélémy Lovant decided to rebuild the Abbey in superfluous luxury: the Gothic abbey church was given a Baroque-style facade, it was given its own factories, a tannery, a brewery, and some enormously luxurious guest houses.

It was not until 1775 that the restoration was finally completed, but in 1794 Aulne was destroyed by the violence of Napoleon’s French Revolution, leaving only a ruin. During this revolution, the magnificent library also went up in flames, forcing the monks to retreat to a neighboring abbey.

In 1859, when the last monk finally died, certain parts of the ruins were restored and given a new purpose: a retreat house. A new Saint Joseph’s Church was also built with the material from the ruins.

In 1950, the old brewery “Brasserie de l’Abbaye d’Aulne” was brought back to life. The Brasserie still produces Belgian specialties (“Blanche de Charleroi“), respecting the brewing tradition of the Cistercian monks of the Aulne abbey.

In 2006, the Region of Wallonia finally decided to buy the Abbey and classify it as a historic landmark. The former stables of the Abbey are still used today as a brasserie (“Val de Sambre”).

Blessed Simon of Aulne Abbey

In the 12th century, Simon of Aulne lived in the Abbey, where he was assigned to work in the monastery granaries and tend the sheep. During his time at the Abbey, Simon became a mystic who experienced visions and was believed to have the gift of reading hearts.

Simon’s reputation spread like a wildfire, and was summoned in 1215 by Pope Innocent III to visit the Vatican in Rome and advise the Pope during the Fourth Lateran Council. After the Council, Simon returned to Aulne where he died at the age of eighty-four.

Essential facts about Aulne Abbey
