WIGTOWNSHIRE, SCOTLAND—Road construction in southwest Scotland has uncovered evidence of human settlement in the area dating back 9,000 years. Among the discoveries are two necklaces made of jet beads that date to 2000 B.C., a brooch dating to the Roman period, a Bronze Age cemetery complex, and an Iron Age village. The necklaces had been made in North Yorkshire and are the first of their kind to have been found in southwest Scotland. “In addition, numerous smaller sites have been discovered which seem to relate to the use and exploitation of the land both through hunting and farming,” Rod McCullagh of Historic Scotland told The Scotsman.
