Dun Trodden Broch

We returned home from Skye via the Glenelg Ferry and took the opportunity to visit two brochs nearby. It's amazing to think these roundhouses were built between 2,300 and 1,900 years ago.

Here's a blip of one and some information from Wikipedia:

A broch is an Iron Age drystone hollow-walled structure of a type found only in Scotland. Brochs include some of the most sophisticated examples of drystone architecture ever created, and belong to the classification "complex Atlantic Roundhouse" devised by Scottish archaeologists in the 1980s.
