The complex was established as a Commandery for the Teutonic Knights in the 13th century.
The current main residential building, the 'Water Castle,' is primarily an 18th-century structure built in Louis XV style.
The on-site English garden, designed in 1786, was one of the first of its kind in the Southern Netherlands.
During the 1971 fire, the interior of the main castle was almost entirely destroyed, necessitating a complete interior rebuild.
The site hosts a unique 'Bible Garden' featuring plants mentioned in biblical scriptures.
It served as a base for the Teutonic Order's military and administrative expansion in the Meuse-Rhine region.
Alden Biesen is a historic castle complex in Bilzen, Belgium, formerly serving as the headquarters of the Teutonic Order's Land Commandery of Biesen. The site now functions as a government-run cultural and conference center hosting international events, seminars, and exhibitions. The architecture spans several centuries, featuring a 16th-century moated castle, an 18th-century French garden, and an English-style landscaped park. Significant sections of the complex were destroyed by fire in 1971, leading to extensive restoration efforts that concluded in the late 20th century. The estate covers over 40 hectares, including historic orchards and an arboretum. It remains a venue for the annual European Storytelling Festival. The site is owned by the Flemish Community and serves as a heritage hub for cross-border cooperation.
