Historic Environment Scotland (HES) (Scottish Gaelic: Àrainneachd Eachdraidheil Alba) is an executive non-departmental public body responsible for investigating, caring for and promoting Scotland’s historic environment. HES was formed in 2015 from the merger of government agency Historic Scotland with the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS). Among other duties, Historic Environment Scotland maintains more than 300 properties of national importance including Edinburgh Castle, Skara Brae and Fort George.
