neolithic farming brought permanent settlements. at balbridie in aberdeenshire crop markings were investigated, and ditches and post holes found, revealing a massive timber-framed building dating to about 3600 bc. an almost identical building, with evidence of pottery, was excavated at claish near stirling. on the islet of eilean domhnuill, in loch olabhat on north uist, unstan ware pottery suggests a date of 3200–2800 bc for what may be the earliest crannog.
