The oldest known dwellings of our region are the stone age caves near the train station of Liesberg.

They were rediscovered in 1874 during the construction of the train line from Basel to Delsberg and were then used as tool shed and smithy.

The importance of this site became known only at a much later stage, when old bones and flints were found. These items where sold to various museums in the region. The oldest encampments were dated back to the early stone age (500.000 to 100.000 B.C.), most finds however dated back to the late stone age (40.000 to 5.000 B.C.). During World War One the caves were once again inhabited, when they were used as temporary shelter by roving gypsies, who offered their services as knive sharpeners and basket makers.
