The unusual and perhaps distinguishing fact about St. Marys church is the evidence of continuous worship within the building stretching almost 900 years. There are some outstanding historical relicts dating from the previous Saxon church, through to present times. Amongst these relics are stone coffins from the thirteenth century with perhaps the most elaborately decorated example of early English carving of a floriated cross produced at the nearby quarry of Barnack. Within these coffins were the remains of two priests, whose remnants of both Chalice and Paten are displayed in a cabinet inside the church.

Further evidence of the importance of the church in bygone times are the two tile fragments unearthed when the impressive Heraldic Suite rooms were being constructed. One of these tile fragments has been identified through the British Museums tile collection as being part of ?The Nottingham Tile. It is thought that these tiles were once used to cover a floor within one of the many Chantry Chapels that could be found within the church during the late Middle Ages (the church is recorded in 1376 as having 10 priests, 2 deacons and a sub-deacon).

Another outstanding feature is the 17th century ten poster tomb of Sir Anthony Irby and his wife Elizabeth, together with their five children. The eldest son (also Sir Anthony Irby) went on to be one of Cromwells leading generals during the Civil War.

Perhaps the most striking feature inside the church are the enormous series of pillars supporting the superstructure, these are clearly out of proportion with the present building and strongly support the theory that the church was indeed intended to become an Abbey Church with a gallery (triforium) at the second level.

It is evident that there are far too many features contained within the one building to record here, however an extended visit to the area which also contains the tallest mill structure within the county at Moulton (the mill is expected to be finished, complete with sails sometime in 2009/2010), the Water Taxi feature on the River Welland, and Ayscoughfee Hall, both in nearby Spalding. There are several highly recommended B&Bs within the area (see details on accommodation page).
