Howe Broch, Stromness
One of the largest excavations ever undertaken in Scotland, this site just outside Stromness seems to have been occupied since Stone Age times. Work throughout the 1970s and 1980s revealed an Iron Age broch and Pictish settlement, which in turn had been built on the remains of two Neolithic chambered tombs. Thousands of artefacts were found, including a glass linen smoother, and many bronze pins and brooches. One brooch, representing an insect in flight, is thought to be Roman in
origin, dating from the 2nd Century. It and many other objects from the Howe excavation are on display in the Orkney Museum. More details of this huge excavation can be found in the Archaeology section.
