Ravenglass is a small coastal village and natural harbour in Cumbria, England, roughly halfway between Barrow-in-Furness and Whitehaven. Historically in Cumberland, it is the only coastal town in the Lake District National Park. It is located at the estuary of three rivers: the Esk, Mite and Irt.
The town dates back to at least the 2nd century, when it was an important naval base for the Romans. The Latin name of the settlement is the subject of scholarly debate: believed by some experts to have been Tunnocellum or Itunocelum, it is often named Glannoventa. It occupied the most southerly point of the Cumbrian coastal defence system, which can be seen as an extension of Hadrian's Wall and the western extremity of the Roman frontier World Heritage Site.
