Stöng, was a real viking-age farm in the Þjórsárdalur valley. One of it's tenants was the warrior Gaukur Trandilsson, who is mentioned in Njál's Saga. In 1104, the nearby volcano Hekla erupted. Stöng was buried, but well preserved, in ash. In 1939 Stöng was excavated, and in the 1970s a replica, called Þjóðveldisbær (Commonwealth farm), was built. It was closed the day we visited.
