The village was originally established as a Roman auxiliary fort named Bremetennacum or Bremetennacum Veteranorum. The first fort was built in timber in AD 72/73 by the 20th legion. The fort was renovated in the late 1st century AD and was rebuilt in stone in the early 2nd century. During the life of the fort, a village grew up around it. A fort remained at Ribchester until the 4th century AD and its remains can still be seen around the present village.
