The rooms of the Dong Ecomuseum showcase countless photos and models. Also visible are the famous closed tower of Mapang (the largest of the region) and the Wind and Rain bridge at Dudong. Some 50m long, it has two levels, one for people and one for animals and is entirely built out of wood. There is also a reconstituted traditional Dong villa and a house on stilts. Visitors can also admire fine collections of jewellery and embroidery.
