The capital, the city of Solothurn, is known as one of the most beautiful Baroque cities in Switzerland. But its origins start way back in celtic times, when it was a fortified town. The Romans left some traces here too, and the Zähringer Dynasty really established the city in 1218. Solothurn remained Catholic after the reformation and so was chosen in 1530 as the residence for the Ambassador of the King of France. Today, Solothurn is a picturesque and active city with many shops and trendy restaurants.


With 17’500 inhabitants Olten is the largest city in the Canton of Solothurn  and best known as the Hub of the Swiss railway system. The old city is rather small compared to the modern city of Olten which developed in the 19th century, thanks to the Industrial Revolution.  Olten presents a broad spectrum of cultural offerings with four museums, two libraries, a swimming pool and the well-known Olten City Theater.


Grenchen is not only home to Breitling, ETA (the world’s leading manufacturer of watch movements), but also to Switzerland’s fourth largest airport. Its main industrial development started in the 1850s with the watch making industry. Many impressive private houses are proof of Grenchen’s successful industrial past. The next big development occured in the 1960s and today one sees medical technology companies thriving beside the watch making companies. The export oriented economy continues to strengthen this village at the foot of the Jura hills. Grenchen is also home to the famous soccer competition, the Uhrencup (watch Cup), played in the Brühl Stadion.
