Skara Brae

Skara Brae is a stone-built Neolithic settlement on the Bay of Skaill, Orkney, Scotland, dating to 4500–3000 BC[1]. The village consisted of ten clustered houses constructed from local flagstones, supported by earthen dams[1]. Each dwelling featured stone-built beds, hearths, and cupboards, demonstrating sophisticated domestic planning[1]. Notably, the settlement possessed an advanced sanitation system with individual toilets and drains that channeled waste to the sea[1].
