One of the treasures of Partrishow is its exquisite Rood Screen, carved out of Irish oak. At the rear of the church is an unusual dugout parish chest carved out of a solid tree trunk, with iron bands around it and three locks, once used for the safe keeping of parish valuables. The Rector and church Wardens each held a key to one of the three locks, so the chest could only be opened when the three were present.

The churchyard was originally very small, but has been extended in the last hundred years and now stretches as far as the lane.
It retains a medieval churchyard cross and is still used for modern burial.
