Cilurnum

Cilurnum or Cilurvum was an ancient Roman fort on Hadrian's Wall at Chesters near the village of Walwick, Northumberland. It is also known as Walwick Chesters to distinguish it from Great Chesters fort and Halton Chesters.

Cilurnum is included in the Notitia Dignitatum of the late 4th/early 5th century.

Cilurnum is considered to be the best preserved and best example of a Roman cavalry fort along Hadrian's Wall. The site is now preserved by English Heritage as Chesters Roman Fort. There is a museum on the site housing finds from the fort and elsewhere along the wall.
