Solothurn relocation checklist
Solothurn • German • Updated August 2026
Solothurn is the German-speaking Mittelland canton wedged between Bern, Aargau, Basel-Landschaft and Jura. The cantonal territory is unusually split — two main blocks separated by enclaves of Bern — which gives the canton an odd shape on a map but in practice means three economically distinct sub-regions. The baroque capital, also called Solothurn, sits on the Aare and is one of the best-preserved historic towns in Switzerland. Olten is the canton's rail hub (more InterCity trains pass through than almost any other Swiss station). Grenchen anchors the western watchmaking belt and is home to Breitling, ETA and several other industry names.
