Laxton, Notts

Famous for its surviving remnants of the mediaeval open field system,it also has a large church, which underwent some restoration in Victorian times. 

I'm not sure they're making the most of the tourist potential!

There are the mounds of a motte and bailey with a wide view. Access via a very muddy bridleway.

It's also one of the highest points in Nottinghamshire - not an upland county.
