The single-nave church of Alden Biesen is unique and exceptional: it is one of the few remaining houses of prayer of the Teutonic Order. The baroque high altar is executed in black and white, the colours of the Teutonic Order. In front of the altar lies the Gothic tombstone of Edmund von Werth, a bishop of the Teutonic Order buried in Alden Biesen in 1292. On the left side altar there’s a high Gothic statue of the Madonna with child, the patron saint of the Teutonic Order and worshipped here as a miracle statue since 1270.
