Werdenberg

Werdenberg was a Swabian county of the Holy Roman Empire, centred on its castle above Grabs and holding Bludenz. In 1337 Albert I of Werdenberg-Heiligenberg ruled it.

His grandsons divided their inheritance between 1377 and 1387 into the Werdenberg, Rheineck, Bludenz and Heiligenberg branches. The county was pledged in 1402 and bought by Lucerne in 1485. Lucerne sold it to Glarus in 1517; the territory joined St. Gallen in 1803.
