Old Moray House. Built in 1625 by the Countess of Home, this building was inherited by her daughter, Margaret, Countess of Moray in 1643. Margaret's improvements to both house and garden made it the "Handsomest house in Edinburgh". The house has historical associations with Argyle, Montrose and Cromwell and the garden with the Signing of the Union. In 1848 the house was purchased from the North British Railway Company to become the Free Church Teacher Training College.
