Lying in Holyrood Park, beneath Salisbury Crags towards Holyrood Palace in Edinburgh, is St. Margaret's Well. The well dates from the late mediaeval period and consists of a vaulted-chamber with water delivered through a spout emanating from the mouth of a grotesque mask. It is thought to have been modelled on St Triduana's Well in nearby Restalrig, which was close to the original site of the well. The well originally lay at Jock's Lodge. Its was moved stone-by-stone in 1859 to allow the St. Margaret's Workshops to be extended for the North British Railway Company. The workshops have subsequently been replaced by St. Margaret's House, a government office, but the site of the well is marked by a monument in the form of a boulder.
