The oldest traces of settlements in Laupen is some Bronze Age sword blades which were found in a gravel pit and two grave mounds at Holzmatt-Laupenholz. Roman era coins, weapons and vessels were found north of Laupen town and at Zollgässli, while traces of a Roman road have been found at Laupenmühle. The remains of the supposed "Roman" Saane bridge downstream of the confluence of the Sense and Saane rivers Sarine have been recently dendrochronologically dated to the period around 1400.
