This curious box-like Norman church stands between the very busy A45 and the grounds of Upton Hall, now a school.
There are several memorials and hatchments mostly commemorating the Samwell family as well as effigies of Sir Richard Knightley (who died in 1537) and his wife, and a monument to the author of Oceana, James Harrington (who died in 1677).
Mounds and other signs of a deserted nearby Medieval village can be seen around the church.
