The Commandery of Sint-Pieters-Voeren is a castle in Maasland Renaissance style and a former commandery of the Teutonic Order, located within the bailiwick of Biesen. Upon his entry in 1242, Daniël van Voeren donated all his possessions to the Teutonic Order. This had already been established in the County of Loon in the bailiwick of Biesen since 1220. Until the French Revolution, the territory of Sint-Pieters-Voeren would remain an enclave in the county of Dalhem as an imperial lordship under the authority of the Holy Roman Empire (Roman-German Emperor). The castle complex consists of a farm building, stables and a gatehouse. All this in the shape of a rectangle grouped around a courtyard, in the middle of a park. In the farm, Voerense syrup is prepared in large copper kettles over a wood fire according to an old recipe. The original ring canals still exist and were expanded in 1885 with a number of ponds where trout, sturgeon and eel are bred. The river Voer, which gives its name to the region, rises on the site.
