Although it is said that the Congress of Vienna (1814-1815) settled the frontiers of Switzerland, Austria and Switzerland stubbornly disputed control of twenty square kilometres in an area around the village Tschlin in Graubünden. The Austrian emperor’s commitment and compromise finally led to the solution in 1868 and the last major border adjustment of Swiss territory. The exhibition tells this fascinating, but forgotten story. With the creation of the border, smuggling also arose. Swiss, Austrians and Italians continued this trade well into the 20th century. The exhibition presents typical contraband goods and smuggling equipment.
