Isle of Lewis

Standing stones and stone circles witnessed this early occupation, as did the Iron Age fortresses and archaeological sites scattered on the island. The tributaries we see today, the mountain fortresses, and evidence of the Iron Age were built around 250 BC. By 500 AD, it was mainly on the coastal edge. We observe that Lewis has large areas of peatland and swamps. However, this is not always the case. Until 1500 BC, the island was fertile, warm, and less humid. Farming is predictable and safe, and seafood is abundant. Before this, most of the megaliths and stone circles were being constructed.
