Aballava or Aballaba (with the modern name of Burgh by Sands) was a Roman fort on Hadrian's Wall, between Petriana (Stanwix) to the east and Coggabata (Drumburgh) to the west. It is about one and a half miles south of the Solway Firth, and its purpose was to guard the south end of two important Solway fords, the Peat Wath and the Sandwath, which were also to become favourite routes for medieval border raiders. There was a vicus to the south-west of the fort, and it is believed that a cemetery existed to the south of the fort.
