St Luke's Church was built in 1331, originally founded as a chantry by Edward III around 1330, and was said to have been built on the site of an ancient (possibly Saxon) chapel. The tower is of the original 14th century, and is most unusual insofar as it appears to be two in one - a hexagonal turret with a square tower behind. This may have something to do with rebuilding over the centuries, as the most current part dates from 1897.
Interestingly, one of the earliest written records is the granting of a Royal Charter in 1252, to allow a three-day fair at St Luke’s-tide on the 18th of October, which could explain in part why the church was dedicated to St Luke.
These two photos (above and below) show the use of large pebbles in the flint rubble wall and can also be seen in the Pebble Buildings page and album. Popple is an old Devon word for pebble and the original meaning of Newton Poppleford is 'new town built by a pebble stream'.
I only had a short amount of time until my bus was due when I took these photos, and was unable to take up the opportunity of an open door. Unfortunately the door has been locked on subsequent visits, but I will add some interior shots as soon as they're available.
A few more photos can be seen in the Photo Gallery album along with these.
