The word ‘broch’ derives from the Norse borg (“fort”) and is used by archaeologists to describe the circular, prehistoric drystone towers found mainly in the north and west of Scotland. Dun Telve (above), which is near the village of Glenelg on the Lochalsh coast, opposite the Isle of Skye, is a good example.
Broch of Mousa - the finest preserved example of a broch or round tower in Shetland, Scotland. It is the tallest still standing in the world and amongst the best-preserved prehistoric buildings in Europe. It is thought to have been constructed circa 100 BC, one of 570 brochs built throughout Scotland. The site is managed by Historic Scotland.
