The local history museum covers the archaeology of the Hanság marshlands, the Roman frontier, and the agricultural history of the Moson plain. The collection is modest but well-labelled, and a visit takes an hour at most. Captions are mainly in Hungarian with some German; English is patchy.
The museum sits in a 19th-century townhouse on the main pedestrian street and makes a sensible stop on the way between the castle and the church square.
