The Ring of Brodgar is a cool Neolithic site in Scotland, specifically on the Orkney Islands. It's basically a big circle made of standing stones that dates back to around 2500-2000 BC. Some say it's like a mini Stonehenge, but with a perfect circular shape. There are about 27 stones left standing out of the original 60, and the whole thing sits between two lakes. Archaeologists are still trying to figure out its exact purpose, but it's definitely a fascinating spot with a lot of history!
