In the quiet valley of Glenelg stand two Brochs from the early time of the Picts (approx. 100 AD). What the towers exactly served for, is unclear. Very impressive is the construction: no mortar connects the stones, they are only stacked up. Double-walled the buildings rise in form of a cooling tower till 12 meter height. Brochs exist only in Scotland. The best preserved brochs stand on the Shetlands Islands, the Outer Hebrides and here in the valley of Glenelg.
