Thierstein

The Thierstein counts sit at Alt-Thierstein above Gipf-Oberfrick in the Frickgau and, since the Saugern inheritance of about 1180-1190, hold estates in the Birs valley south of Basel where the later Neu-Thierstein castle (rebuilt 1294-1295) stood.

They are at times high advocates of the bishopric of Basel.
