Where Is Exham Priory, England?

Exham Priory is in England, near a town called Anchester, and that is all the account will guarantee. Anchester appears on no current survey. The Archive places the Priory in the Severn borderland, south of Gloucester and north-east of Bristol, and the Field Survey marks that position as conjectural: a pin with a wide shaded zone around it, the pin deliberately kept off-centre.

Why the Archive files it VERIFIED but charts it as a conjecture

The two marks answer different questions. The VERIFIED stamp records that the estate is an ordinary place, a restored medieval priory of the kind that can be found by any visitor who is given the county. The conjectural mark records that nobody has given the county. The Archive's reasoning rests on three details in the account: Anchester was a camp of a Roman legion; the foundations beneath the Priory carry what the account calls "Cymric" work, which suggests the west of England; and the Priory lies three miles west of Anchester.

The pin sits about fifteen miles south of Gloucester and twenty miles north-east of Bristol. The zone covers southern Gloucestershire, northern Somerset, Bristol and Bath, and the Welsh edge at Newport and Cardiff. The Archive treats the position as the most it can defend.

What lies under it

The estate was restored by its heir, who had inherited it from the family line and crossed from America to take it up. The villagers avoided the house. Its sub-cellars descend through Roman and then pre-Roman construction into something that is not architecture in any ordinary sense. This office would not recommend a survey.
