The Siuntio Museum tells the story of the area’s history on the slopes of Krejansberget in the church village. The museum complex consists of seven buildings, and most of the collections are housed in the former schoolhouse. The grounds also feature granaries and an old farmhouse. The museum is maintained by the local heritage association Hembygdens Vänner i Sjundeå. Visits in the fall must be arranged in advance with the museum via email or phone. Free parking is available on the museum grounds, but the museum facilities are not wheelchair accessible. Online ticket sales are currently unavailable; tickets can be purchased at the museum in cash.
