SU9377 : St Mary Magdalene church, Boveney

This attractive but disused church stands by the Thames Path, and is now maintained by the ‘Friends of Friendless Churches’.
Most previous photos of the church have been entered for square [[SU9477]]. My own GPS readings suggested that the west (left hand) end was about 12 metres inside SU9377, so probably the 94 eastings grid line bisects the church! But we know that hand-held GPS units have a margin of error, an error which is greater than the quoted accuracy unless the unit is given 5 or 10 minutes to ‘settle’. Whatever the true position, I cannot criticise any previous submitter for their choice of square, whichever it was.
