Most stone altars were removed from Anglican churches during the reformation so it is remarkable that this one has remained in tact.  When the priory was restored in the 1980s this stone was recognised as being a former alter stone.  It had at one time been used as a tombstone and the large square that can be seen is where a brass plaque was mounted when it was used as such. The brass plaque can be seen on the wall above the altar.

On the centre of this square there is a deep indentation where it is thought that a sacred relic may have been housed and covered by a stone ’seal’.  Five crosses, blessed with holy oil at the consecration of the altar are cut out, one in each corner and one to the centre right of the stone.  They represent the five wounds in the body of the crucified and risen Christ.
