Stadtfest Solothurn: Inside the Baroque Old Town’s Biggest Party

Once every two years, the quiet cobblestone streets of Solothurn’s old town stop being quiet. Fountains that normally just trickle become gathering points, the Kreuzackerplatz fills with a Ferris wheel, and the Aare river gets a soundtrack of live concerts drifting over the water until two in the morning. This is Stadtfest Solothurn, the city’s own street festival, and if you search for it, you are probably trying to figure out one of three things: when the next edition happens, what actually goes on for three days straight, or whether it is worth planning a trip around. The short answer is yes. Here is everything you need to know.

What Is Stadtfest Solothurn?

Stadtfest Solothurn is a free, three day city festival held across roughly ten locations in and around Solothurn’s old town, from the Hauptgasse to the Kreuzackerplatz to the banks of the Aare itself. It runs under the motto “Üses Fescht, from Solothurn for Solothurn,” and that phrase is not just branding. The entire festival is built around local associations, artists, restaurants, and businesses rather than outside promoters, which gives it a genuinely homegrown feel that is increasingly rare for a festival of this size. There are no tickets and no entry gates. Instead, organizers sell optional solidarity wristbands in silver, gold, and a premium red tier that also gets you free regional public transport and a discount on the local boat line, and the funds raised go directly toward running the event.

The program mixes everything a Swiss summer weekend should have: a packed concert lineup on multiple stages, a giant children’s and family zone, market stalls from regional producers, guided tours, a giant wheel over the Kreuzackerplatz, a zipline across the Aare, artistic swimming performances in the river itself, and, in 2026, a brand new addition, a 111 meter brunch table stretching across the Postplatz for what organizers call the longest brunch in Solothurn.

From the Märetfescht to a New City Festival

Stadtfest Solothurn did not appear out of nowhere. It is the direct successor to the Märetfescht, a long running Solothurn tradition that quietly wound down after its final edition in 2019 once the organizing committee could no longer keep it going in its old format. For a few years after that, the city’s summer calendar had a noticeable gap, and locals kept asking the same question: would Solothurn ever get its street party back?

The answer took shape slowly. The Stadt und Gewerbevereinigung Solothurn began planning a replacement event, originally hoping for a launch in 2023, but the premiere was pushed back a full year once it became clear that organizing a festival of this scale needed more preparation time. The wait paid off. The first ever Stadtfest Solothurn finally took place from June 28 to 30, 2024, under organizing committee president Alain Blaser, and it turned out to be exactly the comeback the city had been hoping for.

The First Edition: June 2024

The debut Stadtfest leaned heavily into local culture. The program included guided tours through “hidden Solothurn,” old film footage of the city shown at Kino Palace, a secondhand fashion show on Löwengasse, and, in one of the more memorable images from that weekend, a synchronized swimming display performed by Solothurn’s own artistic swimmers right in the Aare in front of the Landhausquai. Sunday brought a flea market in the Kollegiumhof, karaoke on the Friedhofplatz, and the very first Stadtfest brunch. The weekend closed with homegrown rapper Manillio headlining the main stage on the Kronenplatz.

Roughly 40,000 people showed up over the three days, a huge number for a town of Solothurn’s size, and the reception was overwhelmingly positive. Local press called it proof the city “hadn’t forgotten how to celebrate,” and the organizing committee came away confident enough to start planning a second edition almost immediately. One detail from that first year still lives on today: the festival’s colorful banners and tent canopies were later repurposed, in partnership with the Stiftung Solodaris, into handmade bags and accessories sold as a small, sustainable keepsake of the 2024 event.

Stadtfest Solothurn 2026

The second edition ran from June 26 to 28, 2026, this time spread across ten locations with Friday running 4pm to 2am, Saturday from 1pm to 2am, and a calmer Sunday from 10am to 5pm. The Kreuzackerplatz once again became festival command central for families, run by the Stiftung 3FO under the theme “üsi Ching, üsi Zuekunft,” meaning “our children, our future.” It hosted a craft and trades village, an eleven-station challenge with games and puzzles across the grounds, face painting, a Ferris wheel, and, new for this edition, a dedicated youth zone by the H4 Hotel with retro gaming, a street soccer pitch, and a pump track for skateboards, scooters, and bikes.

Music-wise, the standout moment came Friday evening when Veronica Fusaro, who represented Switzerland at Eurovision 2026 in Vienna with her song “Alice,” played the Kreuzackerplatz stage in front of a packed crowd. Saturday brought a different kind of highlight when the Stadtorchester Solothurn performed a full concert of film score classics, complete with a genuine DeLorean and Batmobile replica parked nearby courtesy of the Enter Technikwelt Solothurn. Down on the water, Solothurn’s own pump foilers, considered among the best in Switzerland, put on a demonstration and contest on the Aare, and the city’s artistic swimmers returned for another river performance, this time with a choreography created specifically for the festival.

The big new addition for 2026 was the 111 meter brunch table on the Postplatz, shaded by the square’s old trees, where visitors sat down together for what the organizers billed as the longest brunch the city has ever hosted. The Öufi brewery, Solothurn’s own local beer named after the city’s beloved number eleven, released a dedicated Stadtfest beer for the occasion, and three city bakeries teamed up on a limited edition Stadtfest sablé cookie, with part of every sale going back into funding the festival.

There was one challenge organizers could not plan around: the weather. The 2026 edition landed squarely in the middle of a summer heatwave, and daytime temperatures pushed the city to add nine drinking water and refreshment stations, three mobile showers with drinking fountains attached, extra sun umbrellas and shade structures on the Klosterplatz and in the Kreuzackerpark, several large fans placed around the festival grounds, and more than 4,000 free sunscreen samples handed out at the info stands. According to the post-event coverage, both the organizing committee and the city police called it a peaceful festival overall, with the heat dampening the daytime mood a little but doing nothing to stop the evenings from filling up as planned.

Getting Around and What to Expect

Because Stadtfest Solothurn spreads across the entire old town rather than a single fenced site, half the fun is simply wandering between squares. The Hauptgasse hosts a small producer’s market with regional goods, the Kronenplatz and Marktplatz areas anchor the bigger concerts, and the riverside becomes its own attraction once the sun goes down. Payment at food and drink stands is mostly cashless, working with Twint or card, though the reusable cup deposit of two francs is always refunded in cash. If you are coming from out of town, the red premium wristband is worth considering, since it includes free regional public transport for the whole weekend on top of the usual perks.

Because it is genuinely a city wide event rather than a fenced festival ground, Stadtfest Solothurn pairs naturally with everything else the old town already does well. The restaurant scene that normally fills every square meter of the Altstadt simply extends its tables a little further onto the street, and the same terraces, pizzerias, and cafés that make Solothurn’s food scene so reliable the rest of the year keep serving right through the festival weekend.

Why Solothurn Needed a Festival Like This

To understand why Stadtfest Solothurn matters so much to locals, it helps to know what came before it. The Märetfescht was not just another summer event, it was a Solothurn institution for decades, the kind of weekend that clubs, sports associations, and neighborhood groups built their entire year of fundraising around. When it disappeared in 2019, the loss went beyond a missing party. Local associations lost a reliable source of income, and the city lost one of its few moments where the entire old town, rather than a single street or square, became one shared gathering space.

That gap is part of what makes Stadtfest Solothurn feel less like a brand new event and more like a homecoming. The organizing committee deliberately built the new festival around the same principle that made the Märetfescht work for so long: local clubs, artists, and businesses running their own stands and stages rather than an outside company parachuting in a generic festival format. It is also why the festival does not happen every year. Organizers have been upfront that pulling off an event of this scale, spread across ten locations with dozens of volunteer organizations involved, needs the kind of lead time that only a two year cycle allows. That deliberate pacing seems to be part of the appeal rather than a limitation. Missing an edition means waiting, and that waiting appears to be exactly what keeps the anticipation, and the turnout, so high each time.

Practical Tips for Visiting

If you are planning to attend a future edition of Stadtfest Solothurn, a few things are worth knowing in advance. Accommodation in the old town books up quickly once dates are announced, so reserving a room early is worth it if you want to stay within walking distance of the action rather than commuting in each day. Public transport is the easiest way to arrive, since the old town itself is car free and the festival spreads across streets that would otherwise be difficult to park near. If summer heat is a concern, plan your day around the cooler morning and evening hours, since Solothurn’s stone squares can get intense in direct sun during a heatwave, as the 2026 edition demonstrated. Bring a refillable water bottle. Free drinking water is available throughout the festival grounds, both from the old town’s historic fountains, which stay in operation the entire weekend, and from dedicated refreshment stations set up specifically for the event.

Families with young children will find the Kreuzackerplatz the easiest home base, since it concentrates the children’s programming, shaded rest areas, and food stands in one place, while still being close enough to the rest of the old town for an evening stroll to the main stages once the kids are asleep. Anyone hoping to catch a specific concert or performance should check the published stage schedule ahead of time, since headline slots like the 2026 Veronica Fusaro concert draw large crowds early.

Is Stadtfest Solothurn Worth Planning a Trip Around?

If you want a genuinely local Swiss festival rather than a heavily commercialized event built for tourists, yes. Stadtfest Solothurn is free to attend, easy to reach from Zurich, Bern, or Basel, and gives you a version of Solothurn that only exists once every two years, when its baroque squares turn into stages, its river becomes a swimming and pump foiling arena, and its bakeries start selling limited edition cookies just for the occasion. It captures something the city does especially well the rest of the year too: bringing people together around good food, good music, and a shared sense of place. Mark the next edition on your calendar, book a room in the old town early since it fills up fast, and expect a version of Solothurn that is louder, warmer, and more crowded than usual, in exactly the way a proper city festival should be.
