Its name in Latin is unknown, although it has traditionally been identified with Causennis or Causennæ, a name which occurs as a town on the route of Iter V recorded in the Antonine Itinerary.
It lay on Ermine Street, a major Roman road heading north from Londinium (London) and, after the army left, expanded rapidly in the early 2nd century into a small town.
The trail is accompanied by a booklet ‘Ancaster a Roman Town’ by Jenny Stevens and Henny Shotter.
A dig by archaeological television programme Time Team in 2001 revealed a cist burial partly constructed with a re-used inscription to the god Viridios.
The dig also uncovered Iron Age to 3rd-century pottery, a 1st-century brooch and some of the Roman town wall.
