St. Helen’s Well, approximately 3 miles WNW of Tadcaster, is marked on older OS 1:25000 maps at Grid Ref. SE 452 458, a point now immediately south of Thorp Arch Trading Estate and on the north bank of the river Wharfe. At this place there are a few springs and a little stream running S alongside the agger, or embankment, of a Roman road which crossed the Wharfe by a ford immediately to the S; the Roman road was that between Lagentium (Castleford) and Isurium (Aldborough), that is, not the road to York. The road and ford seem to have continued in use, with a chapel built to serve medieval travellers.
‘St Helen’ is incorporated in several place-names on modern maps, and Healaugh church until recently used the dedication ‘St Helen and St John the Baptist’, and before that to St Helen alone (Raine 1873). The nearest churches are Thorp Arch, one mile; Wighill one and a half miles, and Healaugh, three miles. The course of the Roman road is often called Rudgate because of the reddish soil which forms on the Magesian limestone, and the use of this 'raddle' in plaster.
There are no remains of the chapel but the site is included because it was the find-spot of a carved shaft, now in the church at East Marton, some 35 miles to the E. A full description of the find, with photographs, will be found in that site report.
