Calton Hill was the location of the notorious Calton Jail, a complex comprising a Debtors' Prison, the Bridewell (1791–96) by Robert Adam (later replaced) and a Felons' Prison of 1815-17 by Archibald Elliot. The prisons were replaced by Saughton Prison and demolished in 1930 providing a site for St. Andrew's House, home to Scotland's senior civil servants. The sole surviving building is the castellated and turreted Governor's House by Elliot. The lower curtain walls of the prison are still visible on the south side of St. Andrew's House, above Calton Road.
