some lie on private land). Pictish Symbol stones have been found throughout Scotland, although their original locations are concentrated largely in the North East of the country in lowland areas, the Pictish heartland. During the period when the stones were being created, Christianity was spreading through Scotland from the west and the south, through the kingdoms of Dál Riata, which included parts of Ireland, and the extension into modern Scotland of the Anglo-Saxon kingdoms of Bernicia and Northumbria. Areas that show particular concentrations include Strathtay, Strathmore, coastal Angus, Fife, Strathdee, Garioch, Moray, Strathspey, Caithness, Easter Ross, the Hebrides, Orkney and Shetland. Two Pictish Class I stones are known to have been removed from Scotland.
