The Roman fort of Trimontium (Newstead) stands on the line of Dere Street. The site is marked by a Roman style ‘altar’ erected in 1928 by the Edinburgh Border Counties Association. A series of interpretation boards help visitors to make sense of the setting. The road that cut across the fort has now been closed to traffic and allows easy access.
The Latin name is taken from the three hills, i.e. the Eildon Hills.
Small finds from the site are displayed in the museum at Melrose Abbey.
