Trimontium (Newstead)
Trimontium was a Roman fort complex located at Newstead, near Melrose, in the Scottish Borders, beneath the three Eildon Hills which almost certainly gave it its name (Latin: trium montium, three hills). It was occupied intermittently from about 79 to 184 AD and was the largest of the "outpost" forts after the construction of Hadrian's Wall in the 120s AD. It was located 60 mi (100 km) north of the wall on the extension of Dere Street the main Roman route to the north, initially in seemingly "hostile" territory.
