Roman coastal defense fort in the UK

Alauna was a fort in the Roman province of Britannia. Today it is known as Maryport in the English county of Cumbria (formerly part of Cumberland).

The fort was first established in around AD 122 as a command and supply base for the coastal defences of Hadrian's Wall at its western extremity. There is substantial remains of the Roman fort, which was the last in a series of forts from Hadrian's Wall to prevent the wall being avoided by a crossing of the Solway Firth. Recent geo-magnetic surveys have revealed a large Roman town surrounding the fort. A recent archaeological dig discovered evidence of a second, earlier and larger fort next to, and partially under the present remains.
