Dunagoil Vitrified Fort
Dunagoil is an Iron-Age fort perched high on a volcanic cliff at the southern end of Bute. It occupies a commanding position, with clear views of the seaways around Bute. High stone and timber walls would have surrounded the fort. At some point these walls burned with such intensity that the rubble core became fused into a solid mass – the process of vitrification. The fort was excavated around 100 years ago and many of the artifacts discovered can be seen in the Bute Museum, including stone and pottery vessels, jewellery and a rare bone whistle with carved decoration.
