12th century watchtower found in Norway

Archaeologists in Trondheim, Norway have discovered the remains of a stone watchtower built in the 12th century during the reign of King Sverre. The tower is believed to have been five stories tall.

The rare discovery is only the second early medieval, non-church-related stone structure found in Trondheim. The tower was mentioned in literature in connection with a massacre that took place in 1206.
