Road station
Ad Lullia
Douriez
Adlvllia, Ad Lullia, was a station on the road to Amiens, on the little river Authie in the north of France, today placed at Douriez. The name, At the Lullia, probably preserves an old name of the river, though the map's spelling is surely corrupt. Older research looked for it at Bailleul near Saint-Pol, but the distances lead to the Authie instead. The milestone column of Tongeren seems to have named it too, though only its first letters survive there.
