Bollschweil is a municipality in the Breisgau-Hochschwarzwald district, Baden-Württemberg, Germany, located approximately 10 km south of Freiburg.

The earliest surviving written record of the settlement appears in the records of the monastery at St Gallen, dated 838.

The town's subsequent history is closely entwined with that of the aristocratic Snewlin-Bernlapp family, a branch of the Snewlin family which was extremely influential throughout the Breisgau region.

When, in 1837, the Snewlin-Bernlapps died out, the castle and settlement came into the hands of the von Holzing-Berstett family, whose descendants still inhabit the castle.

Between 1087 and his death in 1093, Ulrich of Zell established here the Priory convent of St Ulrich in the Black Forest, but this was relocated to Sölden in 1115.
