Elginhaugh

Elginhaugh was established during or immediately after the Scottish campaigns of Gnaeus Julius Agricola. Its primary role was probably to guard a ford where Dere Street, the important north–south Roman route, crossed the North Esk. Associated coins closely date the fort’s garrison occupation to about AD 79–87, placing it within Flavian consolidation rather than a long-lived frontier system.

Aerial reconnaissance identified the site in 1979. Dr William Hanson then fully excavated the timber fort and much of its large annexe in 1986–87. This unusually comprehensive investigation established Elginhaugh as the most completely excavated timber-built auxiliary fort in the Roman Empire and allowed the layout and changing use of both enclosure and annexe to be compared in detail.

The excavated plan confirmed broad patterns in Roman auxiliary-fort design while exposing variation within them. Stable-barracks housed horses and men together; their number and arrangement indicate the fort was unlikely to contain one standard unit and was probably occupied by a vexillation of cavalry. That conclusion gives the site particular value for understanding how detachments were accommodated during Roman operations.

After the garrison departed, the fort did not simply fall out of use. Its interior was cobbled, two more wells were dug, and ditches were cut across the annexe to funnel livestock. These alterations provide unique evidence that the place continued as an animal-collection centre, while activity in the annexe changed substantially over a relatively short span.

A hoard of 45 denarii was argued by excavators to be a foundation deposit for the principia, supporting a construction date after AD 77–78. David Woolliscroft later questioned that interpretation because only 21 coins formed a secure stacked deposit and its latest coin dated to AD 71. The debate itself illustrates how closely site chronology depends on the context of finds.
