Elginhaugh Roman Fort was a Roman fort of the 1st century AD, located in Midlothian, Scotland.
Elginhaugh is the most completely excavated timber-built auxiliary fort in the Roman Empire. The site of the Flavian (1st century) fort lies 1 km to the west of the modern town of Dalkeith, south-east of Edinburgh. The fort, discovered in 1979 from aerial reconnaissance, takes its name from the nearby hamlet of Elginhaugh.
The primary role of the fort was probably to guard the nearby ford where Dere Street, a vitally important north-south Roman route, crossed the river North Esk, a tributary of the River Esk, Lothian. The fort’s occupation has, through excavation, been closely dated to AD 79-87. The fort, along with much of its large military annexe, was fully excavated during 1986-87 by Dr William Hanson, now Professor of Roman Archaeology at the University of Glasgow in Scotland.
