 One proposal was to create a new stained glass window in St Giles Cathedral another was for an arch on Observatory Road at the entrance to Blackford Hill.The latter idea was adopted after a letter from Lord Rosebery, offering his "emphatic adhesion" to the idea, was published in The Scotsman on 2nd August 1886.In 1888 the Harrison Arch in Observatory Road was built "to commemorate the work and character of Sir George Harrison".
