Unterwalden, translated from the Latin inter silvas, is the old name of a forest-canton of the Old Swiss Confederacy in central Switzerland, south of Lake Lucerne, consisting of two valleys or Talscha
Unterwalden depicted as one of the thirteen cantons in 1572. Its name is Latinized as Sylvania, and its date of foundation is given as 1315, the date of the Pact of Brunnen, taken as the traditional founding date of the Swiss Confederacy until the 19th century. The old flag of Unterwalden is also shown, identical to the later Flag of Solothurn.
