### Heritage sites of national significance

The Ruins of Neuburg Castle is listed as a Swiss heritage site of national significance.
Neuburg Castle was first built during the late 13th century, most likely for the Baron Tumb von Neuburg (Vorarlberg). About 1450 it came under the control of Rudolf von Rappenstein, and at that time was known as Mötteli. In 1496 it was sold to the Bishop of Chur. Then, in 1577 the municipality bought the castle and associated barony. In the 16th century, the site was abandoned and began to collapse.
