Werdenberg is a town with historical town charter in the eastern Swiss canton of St. Gallen. The town of Werdenberg belongs to the municipality of Grabs and is located 0.5 km west of Buchs. It boasts of being the smallest town in Switzerland with around 55-60 residents. Of the around 40 houses, some only serve as holiday homes. Werdenberg is often visited by tourists because of its very well-preserved medieval houses and the museum in Werdenberg Castle. The Werdenberg Castle Festival has been taking place in Werdenberg Castle since 1985.[
The county of Werdenberg included the castle and town of Werdenberg of the same name, the villages of Grabs, Buchs and Sevelen as well as jurisdiction over the Wartau domain (Wartau Castle and village of Gretschins). The noble family of the Counts of Werdenberg split into several side lines in 1277. The actual county of Werdenberg remained with the line of the Counts of Werdenberg-Heiligenberg.
In 1402 they pledged the County of Werdenberg to the Counts of Montfort-Tettnang, from whom it passed to the Counts of Sax-Misox in 1483. In 1485 the city of Lucerne acquired the county and passed it on to the Barons of Kastelwart in 1493. However, the county remained connected to the Confederation through a castle law with Lucerne, even when the county changed hands again to the Barons of Hewen in 1498. Werdenberg also fought on the side of the Confederates in the Swabian War. In 1517 the Barons of Hewen sold Werdenberg to the canton of Glarus for 21,500 guilders.
Glarus administered Werdenberg very strictly as a bailiwick - the Glarus lords were anything but popular in the Rhine Valley. Because of the confusing legal situation between the counties of Werdenberg and Sargans in the Wartau rule, there were repeated disputes between the bailiffs, which in the “Wartau trade” of 1694/95 were brought up to the federal parliament.
With the fall of the old Confederation and the founding of the Helvetic Republic in 1798, Werdenberg became part of the canton of Linth. When this was dissolved again with the mediation constitution of 1803, Werdenberg became part of the canton of St. Gallen.
The town of Werdenberg boasts of being the smallest town in Switzerland with around 55 to 60 inhabitants. Werdenberg is definitely worth a visit because of its very well-preserved medieval houses and the museum in Werdenberg Castle.
