The Calton area was owned by the Logan family of Restalrig but their lands were forfeited in 1609 following the posthumous sentence of treason on Robert Logan. The lands of Restalrig and Calton, otherwise known as Easter and Wester Restalrig, passed to the Elphinstone family. Sir James Elphinstone was made Lord Balmerino in 1604 and in 1673 the lands of Restalrig and Calton were erected into a single barony. In 1725, the western side of Calton Hill was disjoined and sold to the royal burgh of Edinburgh. The eastern end was owned by the charitable institution of Heriot's Trust. Calton remained a burgh of barony (although it was not administered as such) until it was formally incorporated into Edinburgh by the Municipality Extension Act of 1856.
