The Museum of the Swiss Charters of Confederation (German: Bundesbriefmuseum; up to 1992 the Federal Charter Archive) is a history museum in Schwyz. It was built in 1936 as a national shrine for the Federal Charter of 1291, which was believed to be the founding document of the Swiss Confederation. Today, the museum explains the national myth and the actual history of the Old Swiss Confederacy. It features a collection of original documents and flags.
