Ravenglass is a coastal village in the Copeland District in Cumbria, England. It is between Barrow-in-Furness and Whitehaven. Historically in Cumberland, it is the only coastal village in the Lake District National Park. It is located at the estuary of three rivers: the Esk, Mite and Irt. History The village dates back to at least the 2nd century, when it was an important naval base for the Romans. The Latin name of the settlement was long thought to be Glannoventa. The discovery of a lead seal in excavations at the Roman fort during the 1970s named the Cohors Prima Aelia Classica (First Cohort of Hadrian's Marines). This unit is listed in the Notitia Dignitatum as being garrisoned at Itunocelum during the fourth century. Due to this it was suggested that Ravenglass was not Glannoventa but actually the Itunocelum. Since the lead seal was discovered two other objects, a Roman military diploma from the beach by the fort at Ravenglass and a fragment of a Roman altar from Muncaster, have been found. These both name the Cohors Prima Aelia Classica and prove beyond reasonable doubt that Ravenglass was the Roman Itunocelum. The fort 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. Ravenglass was occupied by the Romans for over 300 years and had a Roman garrison (castra) of 500 soldiers. The town was a regional supply point for much of north-western Roman Britain, with a road from Ravenglass over the Hardknott Pass to the Roman forts at Hardknott and Ambleside. The location is featured in The Fort at River's Bend, a book in Jack Whyte's A Dream of Eagles (Camulod Chronicles) series, and is also mentioned briefly in Mary Stewart's Merlin trilogy under the name Clannoventa. Today, there are few Roman remains, with the notable exception of a bath house, known locally as Walls Castle. This is one of the largest remaining Roman structures in England, originally covering an estimated area of by and with walls up to high, though only one end is now visible. Excavations of the rest of the foundations have since been covered and are not visible. The property is now maintained by English Heritage. Approximately a mile's walk from the bath house is Muncaster Castle, which it is believed was built partly
