The Württemberg field camp in front of the Refuge Hotel, which would later be known as the Schwedenschanze, has its origins in 1593 at the time of the Strasbourg Bishops' War. The Duke of Württemberg had the western border of his country guarded by a permanent garrison stationed in the field camp. Many references in old maps and sources suggest that this encampment was in the same place as the Schwedenschanze.
