Archaeologist Dr Euan Mackie at Vaul broch in July 2000

During the 1960s, Dr Mackie excavated the broch at Vaul, finding many artefacts that suggested that the broch was built around 1,900 years ago and periodically inhabited until about 1,700 years ago. It is thought to have been 8 metres high, and remains the only fully excavated broch on Tiree.
