Long Stratton also known as Stratton St Mary is an old Market Town on the Roman road to Caistor. In 1773 during a new construction several Roman urns and two copper coins were found in a gravel pit giving an indication of a rich and colourful past.

St. Mary's church is Long Stratton's local C of E church with an ancient round tower, housing five bells, and surmounted by a short spire. The tower is much older than the church, the latter being rebuilt about 1330, by Sir Roger de Burgh, and his family. In fact it was his brother, a similar sounding Richard de Bourne who had began the reconstruction of the church building in 1319. The east window was decorated with stained glass in 1805. At the east end of the chancel lie effigies of Judge Reeve and his lady who both died in the 1600s. The church has some interesting woodwork, notably the Jacobean pulpit and font cover.

Pride of place is the Sexton's Wheel. With only one other similar wheel in England, the Sexton's Wheel purpose was to determine the day of the Lady Fast, how this was done is a mystery and is still a subject for debate to the present day.  Recently restored is a one-handed turret clock with a preacher's dial of 17th century origin.
