We shall examine some of the building stones of 18th to 20th century buildings on the walk from Lothian Road to The Mound via the Lawnmarket. We shall view the crag of the famous crag-and-tail of the Castle Rock and consider various interpretations of its origin. Contacts between the basaltic plug of the Castle Rock and early Carboniferous sedimentary strata into which it was emplaced will also be seen.
