[ I thought at first it might just be Nuneham Lock (I don’t know if it was a pound lock or not) – but compare the heights of the church steeple in this and the 2002 photo – this is Abingdon Lock.]

Abingdon is one of the most ancient towns of the kingdom; it stands near the junction of the little river Ocke (which rises in the Vale of White Horse) * with the Thames,
* This vale takes its name from an enormous representation of a horse cut in the side of the chalk hills. This singular figure has existed there from time immemorial. It is rude in character; but, inasmuch as that character is precisely similar to the figures of horses on ancient British coins, it is believed to be equally ancient. It has long been the custom of the peasantry to clear it of weeds, and generally to restore it, at certain seasons of the year.
and although now a place of small importance, has played a conspicuous part in many of the most stirring events of British history.
A legendary tale thus describes its origin: —
"At a time when the wretched pagan Hengist basely murdered 460 noblemen and barons at Stonhengest, or Stonehenge, Aben, a nobleman's son, escaped into a wood, on the south side of Oxfordshire, where, leading a most holy life, the inhabitants of the country flocking to him to hear the word of God, built him a dwelling-house and a chapel in honour of the Holy Virgin; but he, disliking their resort, stole away to Ireland, and from him the place where he dwelt is called Abingdon."
It is hardly necessary to state that this derivation is incorrect, and that the name is purely Anglo-Saxon. We give the legend as an example of the fanciful interpolations in early history by the elder chroniclers. *
* "Abingdone" (says Leland in his "Itinerary") "stands on the right side of the Isis, and was of very old time called Seukesham, since Abendune."
The old hospital at Abingdon is founded on the site of the monastery dedicated to the Holy Cross and St. Helena, by Cisa, sister of the king of the West Saxons, in the seventh century: this religious foundation having gone to decay, a hospital was erected in its place by a rich merchant, in the reign of Henry V., named Geoffry Barbour; in the reign of Henry VIII. this and other charitable institutions in connexion with the church were forfeited to the Crown; and the Abbot of Abingdon, being one of the first to acknowledge the king's supremacy, was rewarded for such subserviency by the gift of the Manor of Cumnor, and a pension of £200 a year for his life. Sir John Mason, in the reign of Edward VI., bestirred himself to restore the charity, and in the year 1553 it was re-endowed, and named Christ's Hospital. It then accommodated thirteen poor men and women; the number is now thirty-two.
