Skara Brae, Scotland Photograph by KEENPRESS, National Geographic Visitors peer into the past in the Orkney Islands, where in 1850 a strong storm uncovered the remains of the Skara Brae settlement. Later excavations revealed a complex of stone houses linked by passageways that dates to between 3200 and 2500 B.C. It’s considered the best preserved Neolithic village ever found in northern Europe and is a World Heritage site.
