Solothurn

Solothurn is a canton of quiet elegance and surprising cultural depth, nestled at the southern foot of the Jura Mountains in north-western Switzerland. The canton straddles the River Aare and occupies a strategic position between the Bernese Midlands and the Jura range, offering a landscape of rolling farmland, forested hills, and the dramatic limestone ridges of the Jura to the north. The canton's capital, also called Solothurn, is widely regarded as Switzerland's most beautiful baroque city — a compact gem of Italian-influenced architecture, ornate churches, and elegant town squares that earned it the nickname "City of Ambassadors" from its long history as the seat of French ambassadors to Switzerland.

The canton joined the Swiss Confederation in 1481 as the 11th canton, and the number 11 has become a beloved local symbol — there are 11 museums, 11 fountains, 11 chapels and churches in the old town, and even a clock that displays only 11 hours. The local beer is called Öufi Bier ("Eleven Beer"). This playful numerological tradition reflects the canton's character: deeply rooted in history but never taking itself too seriously. Solothurn's origins stretch back to Roman times, with the settlement of Salodurum established between 15 and 25 BC, making the city over 2,000 years old.

Beyond the capital, the canton includes the industrial and commercial centres of Olten and Grenchen, the artist colony of Dornach with its extraordinary Goetheanum building, and the Jura mountain villages of Balsthal and Oensingen. The region offers excellent hiking, cycling along the Aare river valley, and easy access to the Jura ridgeline trails, making it a rewarding destination for travellers seeking authentic Swiss culture without the crowds of the Alpine tourist belt.

The best time to visit Solothurn is from April through October. Spring (April–May) brings wildflowers to the Jura meadows and pleasant temperatures for walking the old town and the Aare river paths. Summer (June–August) is warm, with temperatures regularly reaching 25–30°C, and is the ideal time for swimming in the Aare, cycling the river valley, and enjoying the outdoor cafés and terraces of the baroque city. The boat service between Solothurn and Biel/Bienne operates from May to September, offering a scenic river journey.

Autumn (September–October) is lovely for hiking in the Jura, with golden foliage and harvest festivals in the surrounding villages. However, this is also when temperature inversions begin, and fog can blanket the Swiss Midlands for days at a time — a phenomenon that can persist from October through February. Winter is cold but manageable, with temperatures hovering around 0°C in the valleys. The Jura mountains receive reliable snow, making them suitable for winter hiking and snowshoeing.

Key local events include the Solothurn Film Festival (Solothurner Filmtage) in January, one of Switzerland's most important showcases for Swiss cinema. The Altes Zeughaus (Old Arsenal) is turned into a giant advent calendar during December, and the farmer's markets every Wednesday and Saturday morning in the old town are a year-round highlight.

Solothurn is exceptionally well connected by Swiss public transport. The main station is served by Intercity trains along the east-west Jura railway axis, with direct connections to Zürich (1 hour), Bern (30 minutes via RBS), Basel (1 hour), Lausanne (1 hour 40 minutes), and Geneva (2 hours). The RBS (Regionalverkehr Bern-Solothurn) provides frequent direct services to Bern, while regional trains connect to Biel/Bienne, Olten, and Moutier in the Jura.

The canton's road network is centred on the E25 motorway, providing fast connections to Bern, Basel, and Zürich. Within the capital, the old town is compact and pedestrianised — easily explored on foot in an hour or two. Regional buses and a tram line serve the suburbs and surrounding villages. Underground car parks (Bieltor, Baseltor, Dornacherplatz) provide convenient parking near the old town.

Distances within the canton are short: Solothurn to Olten is approximately 20 km by rail (15 minutes), to Grenchen about 10 km (8 minutes), and to Dornach roughly 15 km (12 minutes). The boat service to Biel/Bienne takes 2 hours 50 minutes, stopping at Altreu, Grenchen, and Büren. Taxis are available at the station, and cycling along the flat Aare valley is a pleasant alternative for shorter journeys.

The city's restaurant scene is surprisingly diverse for its size, with the old town's Hauptgasse and surrounding streets offering everything from traditional Swiss Stübli to Italian trattorias and contemporary bistros. The riverfront terraces along the Aare are particularly atmospheric on warm summer evenings.
