Housed in a striking traditional building, this museum has a well-presented collection ranging from early North Sumatran civilisations to Hindu, Buddhist and Islamic periods to Dutch colonial-era and military history. There are also sections devoted to traditional occupations such as fishing and farming. Highlights include fine stone carvings and extravagantly carved wooden dragon coffins from Nias, Batak scrolls for fending off misfortune, fine textiles and a keris (ornamental dagger) collection. It’s a short way east of the centre.
