Skara Brae is a stone-built Neolithic settlement in Scotland. As of today, there are 8 known house built into the ground.
Most houses contain a dresser, a few beds and some even had artifacts. The settlement was built between 3180 BC–2500 BC (which makes it older than Stonehenge or the Great Pyramids) and had only been re-discovered in the 1800s. Since many things have left behind, the houses must have been abandoned in quite a hurry. No one knows why.
