St Oswald's Priory
Originally built by Queen Aethelflaed in c.900 AD, all that stands of St Oswald's Priory today are the remains are of the north wall.
The surviving arcade also contains features from alterations and additions made in the twelfth and thirteenth centuries. Aethelflaed of Mercia, daughter of King Alfred the Great, dedicated the church to Saint Oswald the revered Northumbrian king, following her capture of his relics from Barden in Lincolnshire.
As well as founding the church, Aethelflaed also re-planned and refortified Gloucester as a burgh – a walled town capable of defense against the marauding Vikings. The street layout of modern Gloucester follows the tenth century layout, which in turn was influenced by the underlying Roman town.
