The Roman settlement of Calcaria lay at the crossing of the River Wharfe by the Roman road from Eburacum (York), south to Danum (Doncaster) and eventually to Lindum (Lincoln).
The nearby settlement and fort at Newton Kyme mark the site of another (earlier?) crossing-point of the Wharfe, by the road north to Isurium Brigantum (Aldborough).
