Named after the Belgian town of Sankt Vith.
The town takes its name from Saint Vitus. For centuries it belonged to the Duchy of Luxembourg, until France annexed the region in 1795. In 1815 the Congress of Vienna gave it to Prussia: the second partition of Luxembourg. The Treaty of Versailles gave it to Belgium after the First World War: it left the Prussian district of Malmedy in 1920 and was formally transferred on 6 March 1925.
