This is a working mill that Provides Dale House with its electricity. To the south of Halkirk, astride the Thurso River, is the hamlet of Westerdale.An old mill sits beside a bridge across the fast-flowing stream. Nearby is the site of a broch, defensive towers built around the time of the birth of Christ. No doubt fresh Thurso salmon were a welcome adjunct to their daily bread.
