Unable to upload a HWW image,IP not playing! This is the Calanais Standing Stones on the Isle of Lewis in the Outer Hebrides and the most famous of several related stone settings in the Calanais area (including Calanais II, III, and others), forming part of a broader prehistoric ritual landscape. Often called the "Stonehenge of the North," the site features a distinctive cross-shaped arrangement of standing stones made from ancient Lewisian gneiss (some of the oldest exposed rocks on Earth). The main monument (Calanais I) includes:A central stone circle with 13 stones surrounding a tall central monolith (about 4.8–5 meters high). An avenue of stones extending northward (roughly 83 meters long, formed by two parallel-ish rows that fan out slightly). Rows of stones extending east, west, and south from the circle, creating the cruciform (cross-like) pattern The stones were erected around 2900–2600 BC during the Neolithic period—predating the main phases of Stonehenge by several centuries (roughly 500 years earlier than its famous sarsen circle). The central stone circle is shown in the image,,,,,,,,,,,,,,, It really does need a large view for the full effect !
