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 by aerial reconnaissance, takes its name from the nearby hamlet of Elginhaugh. It was fully excavated, along with much of its large annexe, during 1986-87 by Dr William Hanson, now Professor of Roman Archaeology at the University of Glasgow in Scotland.
