Alden Biesen, around 800 years of history and mystery.

What do knights, monks, crusaders, dragons, rats, femmes fatales and an eccentric old gentleman have in common? Answer: Bilzen Mysteries.

The story of Alden Biesen actually starts in… the Middle East. Or more precisely, in the Promised Land – in Acre, Palestine – in 1190.
The Teutonic Order chooses Mary, mother of Jesus, as their patron saint. The order wants to disseminate and defend the Christian faith and constructs a defensive wall of ‘Grand Commanderies’ across Europe. Each Commandery controls another series of commanderies. In our region, the Teutonic Order chooses Alden Biesen, which itself controls 12 other commanderies stretching from Diest to Cologne. The Grand Commandery grows like many abbeys at the time into a symbol of power and splendour.

The Teutonic Order also wants to liberate the holy city of Jerusalem in order to guarantee safe passage for pilgrims. To do this, they embark on a series of crusades. In Bilzen Mysteries we see how the Brethren Knights leave on the Fifth Crusade to Damietta in Egypt. It is the beginning of the 13th century.

When the Teutonic Order sees that the crusades are unsuccessful, they turn their gaze on Eastern Europe, including Poland, where there are still many souls to be Christianized. But this adventure does not come without a struggle…

From the late Middle Ages, the order buries its battle-axes and swords and limits itself to defending Christendom. Until the French Revolution and the Enlightenment in 1794 bring an end to its authority. Alden Biesen is occupied by French revolutionary troops and publically sold. The estate falls into the hands of the Claes family. The 20th century and two World Wars do the Grand Commandery no favours and maintaining the estate costs money, a lot of money, which is no longer there.

A descendant of the Claes family, Squire Armand Roelants du Vivier, puts his heart and soul into saving the estate. But eventually he realizes that the estate cannot be saved by love alone. He is the last, lonely and somewhat eccentric inhabitant. In 1971, du Vivier decides to sell Alden Biesen.

However, on the day of the sale to the Flemish Government, fate strikes a terrible blow. A raging fire engulfs the castle.

Eventually, and after thorough restoration, everything turns out for the best and Alden Biesen rises again like a phoenix from the ashes.
The ashes of many centuries of good deeds but also of blood, sweat, tears, stories and… mysteries.
