Aarau is a small cantonal capital with the pace of a working town. It stands on the Aare at the southern edge of the Jura, 385 metres above sea level. The city counts 22,892 residents at 31 December 2025 and reports 33,000 jobs, a scale that brings commuters, public services, shops and cultural life into a compact centre. The municipality dates its foundation to 1248. A first visit can move from the station into the old town, then out to the river or nearby woodland without treating the place as a mere stop between larger cities.
The old town’s irregular footprint still follows the line of its first wall, built in the thirteenth century; much of the surviving historic fabric dates from the sixteenth and seventeenth centuries. More than 70 painted roof eaves are its best-known detail. Look up along the lanes: carved beams and painted panels sit above shopfronts, cafés and small businesses. They are easy to mistake for untouched medieval decoration, but the local heritage account explains that most of the painted details were added in the twentieth century, while older examples sometimes emerge during restoration. That layered story makes the roofs more interesting than a simple “medieval town” label.
Aarau’s political history is unusually concentrated. In April 1798 it was declared the provisional capital of the Helvetic Republic, and the new national institutions met in the town for several months. When the canton of Aargau was created in 1803, Aarau became its capital. The old government buildings, town hall and central streets still give the town a civic rather than purely residential character. The city’s self-guided map takes visitors past the Obertorturm, the Stadtkirche, the Halde and the Haus zum Schlossgarten, identified by local tourism as the first seat of the modern Swiss government.
Aarau Info, on Metzgergasse, supplies maps, arranges guided walks and helps visitors book accommodation, restaurants and cultural events. The Stadtmuseum Aarau uses photography, film and city history to connect local stories with broader change. Naturama Aargau introduces the region’s habitats and wildlife; the Aargauer Kunsthaus focuses on Swiss art and rotates its displays. These make a rainy-day itinerary easy, but each museum keeps its own opening calendar, so check before setting out. The city also offers guided routes devoted to public art, architecture and the painted gables.
Local traditions fill the calendar. The Bachfischet grew from the annual cleaning of the Stadtbach; its first documentary mention dates to 1526, and 2026 marked the 500-year anniversary. In the modern procession, schoolchildren carry lanterns through the darkened old town. The Maienzug brings a summer procession and community celebration. In autumn, the Rüeblimärt turns the old town into a market for carrots and regional produce; it takes place on the first Wednesday in November, with the 2026 edition scheduled for 4 November. The weekly market and several seasonal goods markets give visitors more ordinary ways to meet local producers.
The Aare provides a green route through the town. Walk along the river promenade, where islands and sandbanks create a quieter counterpoint to the centre, or continue west toward Roggenhausen valley. Its wildlife park combines native and domestic animals, an orchard, a nature trail and a playground, making it a practical family excursion. Paths and forest close to the city offer space for a longer walk or jog; check access information and the weather if planning a full outing.
Aarau’s economy is visible in the contrast between the historic core and its role as a regional employment centre. The city’s own profile reports more jobs than residents. Cantonal administration and public institutions sit alongside retail, culture, health and regional business services. That daily working population helps sustain cafés, events and an active old town beyond the tourist season.
Rail links make Aarau an easy base for the region. SBB lists direct long-distance services toward Zurich, Basel, Olten and Bern; trains run on several corridors, so compare the exact route and timetable for your travel day. From the station, a useful half-day sequence is the old town and its painted eaves, one museum, then the Aare promenade. With a full day, add Roggenhausen or a regional train outing. The town is best appreciated at walking pace, with time to notice how its national history, civic institutions and everyday market life overlap.
