Thetford Church of Holy Sephulcre, Norfolk

English Heritage.
This is the only surviving remains in England of a priory of Canons of the Holy Sepulchre, who aided pilgrims to Christ’s tomb. The ruined nave of their 14th century church was later used as a barn.
Sat-nav can take you to Canons Close in a housing estate, where the back of the site is at the end of a short cul-de-sac to the right. If you arrive there, you may as well look, but a better view can be had from the other side, on the A134, where there are one or two interpretation panels. The walls stand to near original height.
