Dorcestria apud Mercios
Dorcestria apud Mercios, vel simpliciter Dorcestria, aut Dorcastria, (Anglice: Dorchester-on-Thames) est vicus in pago Oxoniense, prope Wallingfordiam,  ad ripam laevam Thamesis fluminis. Sunt circa 1000 incolae vico.

Primi incolae Dorcestriae territorii fuerunt apud colles propinquas, aetate Aënea, quas nunc Whittenham Clumps nuncupantur. Aetate Ferrea Britanni aggerem aedificaverunt, vicum circundantem. Dorcestria fuit olim oppidum Romanum nomine ignoto, sed situm in via inter Callevam et Castra Aelia (hodie Alchester), quod nunc foditur  ab archaeologis Oxoniensibus. Anno 634 Honorius I papa misit Birinum legatum ad regem Kynegilem Saxonum quorundam, eos in fidem Catholicam convertendi causa, et ipse Birinus apostolus Saxonum abbatiam et episcopatum creavit Dorcestriae. Saeculo VII exeunte, Dorcestriam Mercii sustulerunt.
