Trimontium is the name of a Roman fort at Newstead, near Melrose, Scotland, close under the three Eildon Hills (whence the name trium montium). It was an advanced post of the Romans towards Scotland both about 80 AD and after, and again (after an interval of evacuation) from about AD 140 to AD 180.
Excavations by James Curle between February 1905 and September 1910 yielded finds of almost unique importance. These include the foundations of several successive forts, one above the other, which throw much light on the character of the Roman military post; an unparalleled collection of Roman armour, including ornate helmets, and a good series of coins and datable pottery. The whole illustrate the history of the Roman army and that of Roman Scotland very remarkably.
