Headlines were made in 1864 when a group of excavators uncovered evidence of an "ancient British city" near modern-day Edinburgh Airport.
The fascinating find, which included visible remains of numerous dwellings once inhabited by a prehistoric tribe of people, was made at the southern end of Craigie Hill not far from the River Almond and around a mile northeast of Kirkliston.
The initial discovery had been made some time earlier by the pioneering Edinburgh anaesthetist Professor James Young Simpson who in one of his wanderings thought he had observed the indications of an ancient hill fort in the area.
