The time we visited, this was locked, with no indication of where one could find a keyholder. That's a pity, because although Pevsner pronounces that it was 'over-restored' in 1879, it does have a good wallpainting of St Christopher. Still, we were able to wander round the outside and admire the striped roof, and the picturesque half-timbered porch, and the neat tower with nice pinnacles in the typical Cambridgeshire style.
They've recently added a new parish room, which is sympathetically designed and fits in quite nicely. I'll have to try and get back some time.
church locked, no sign of keyholders
