This painting is of Maryport
Maryport in the north-west of England, the town was established around 122 as one of several Roman localities called Alauna.
It was a command and supply base for the coastal defences at the western extremity of Hadrian's Wall.
The town contains substantial remains of the Roman fort, which was the last in a series that stretched southwards along the coast from the wall to prevent it being avoided by crossing the Solway Firth.
Geomagnetic surveys have revealed a large Roman town surrounding the fort.
An archaeological dig discovered evidence of an earlier, larger fort next to, and partially under the present remains.
After the Roman withdrawal from Britain the town would have diminished in size and importance without a military presence.
