The Eildon Hills stand over the fields where Rome built one of its great northern bases. Trimontium was a Roman fort complex, a group of military enclosures and support areas, beside the Tweed, named for the three hills and repeatedly reshaped as the frontier advanced and retreated.
Trimontium matters because it was far more than a single fort. Camps, annexes, massive ramparts, defensive banks and walls, cavalry equipment, pits full of military objects, civilian activity, and a museum at Melrose reveal a frontier settlement whose fortunes rose and fell with Roman ambitions in Scotland.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
Trimontium was first built around AD 79-80 during the northern campaigns associated with Agricola.
The fort complex stood beside Dere Street and the River Tweed below the Eildon Hills.
It was occupied intermittently until about AD 184.
The fort changed role as Rome shifted between Hadrian's Wall, the Antonine Wall, and northern outpost positions.
Railway cutting works in 1846 revealed important Roman finds from pits at Newstead.
James Curle excavated the site between 1905 and 1910.
Bradford University's Newstead Project investigated the site between 1989 and 1997.
The site produced one of the largest caches of Roman military objects in Britain.

What to look for
-
Three-hill setting
The Eildon Hills almost certainly explain the Latin name meaning three hills.
-
Dere Street
Dere Street was the Roman road, a paved military route for movement and supply, that linked the fort to the wider frontier network.
-
Annexes
Annexes are defended extra areas outside a fort, often linked with civilians, workshops, or support activity.
-
Military pits
Deep pits produced armour, horse gear, organic remains, and other Roman objects.
-
Cavalry equipment
Decorated helmets, face masks, and horse fittings point to an important cavalry presence.
