A small lakeside town on the southern shore of Lake Constance, with a partly preserved medieval old town tucked between the harbour and the castle hill. The 16th-century Schloss Arbon, on Roman foundations, has been restored and houses a small historical museum focused on the Roman, early medieval, and industrial periods of the town's history.
Arbon's industrial heritage runs deep — the Saurer truck and embroidery machine works once employed most of the town — and the renovated Saurer-WerkZwei waterfront is now a mixed arts and retail district worth a walk. The lakeside promenade extends 5 km west to the next town, Egnach, and is one of the easier sections of the Bodensee-Radweg.
