Broch of Mousa

The tallest surviving broch and one of the best-preserved prehistoric buildings in Europe, standing 13.3 metres high on the island of Mousa in Shetland. Constructed around 300 BC, its double-walled drystone structure contains six internal galleries reached by a staircase between the walls. The broch features in two Norse sagas: Egil's Saga describes shipwrecked eloping lovers sheltering inside, while the Orkneyinga Saga recounts a siege by Earl Harald Maddadsson in 1153. Managed by Historic Environment Scotland as a scheduled monument.
