Mr Mason also explores the location’s “ominous towers”, including Corstorphine Hill Tower.
Situated close to the hill's summit, the tower was built in 1871 by William Macfie of Clermiston to commemorate the centenary of the birth of Sir Walter Scott. It was gifted to the city in 1932 to mark the centenary of Scott's death.
