The fort at Cramond was located on the River Almond at the point where it flows into the Forth. In Roman times, there was probably a natural harbour here. One suggested interpretation is that Cramond formed a chain of Lothian forts along with Carriden and Inveresk. The fort was established around 140 during the building of the Antonine Wall, and remained in use until around 170 when the Romans retreated south to Hadrian's Wall. When the Roman Emperor Septimius Severus began the last major Roman incursion into Scotland from 205 to 214, the fort was reoccupied and enlarged. Throughout these periods of occupation a civilian settlement seems to have existed outside the fort, and some native occupation of the fort seems to have taken place after the time of Severus into the 4th/5th century and during the early Sub-Roman period. Several Roman inscriptions have been found around Crammond.
The ground plan of part of the fort is laid out in an area of open parkland. Here one can see headquarters building, granaries, workshop, together with other buildings, restored in outline. Information panels at the site link the findings of the last 50 years of excavations and recreate life in the former Roman headquarters and bathhouse.
References:The Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
