Lord Biesen: a special guide!

Lord Biesen was the last private owner of the Grand Commandery. Today he is your guide and narrator in Bilzen Mysteries. You meet him on 8 March 1971, the day that fate dealt Alden Biesen a terrible blow.
Everyone knew Squire Armand Roelants du Vivier as ‘Lord Biesen’. Throughout his life, he fought to maintain the massive property and keep it intact. Gardening, repairing roofs, fixing the plumbing … He did everything himself and no one could stop him.
You can recognise this charming eccentric by his raincoat, rubber boots and dilapidated moped!

The role of Lord Biesen is performed by Jan Decleir.
