Fodor's Expert Review Broch of Gurness (Aikerness Broch)
An Iron Age tower built between 500 BC and 200 BC, the Broch of Gurness stands more than 10 feet high and is surrounded by stone huts, indicating that this was a village. The tower's foundations and dimensions suggest that it was one of the biggest brochs in Scotland, and the remains of the surrounding houses are well preserved.
