The present building is the result of eight centuries of development, repairs and restoration. It retains both its historical qualities (it is a Grade 1 listed building) as well as trying to meet the needs of a worshipping Christian community in the early 21st century.

The building has a number of interesting features including the following:

The Norman arches are of particular note. One forms the south doorway with its good example of “zig-zag” patterning and one separates the Nave and the Chancel with the latter strengthening the arch on the Chancel side.

The Chancel windows are good examples of their kind and the East window retains its original tracery, albeit restored.

The stained glass window at the north end of the west wall, depicting Elijah, is older than the surrounding stone work and the stained glass window at the south end shows St John the Baptist to whom the church is dedicated.

The north aisle was an extension to the original building and the pillars separating it from the nave are of a different style to those separating the south aisle. The modern vestry has replaced the old Chantry chapel.

The site possibly had a Saxon church built on it, however there is no archaeological evidence reported that relates to this period. The original, Norman, building consisted of a Chancel, Nave and South Aisle. The Nave and South Aisle were the same size as the present building, but the Chancel was originally shorter. The Chancel arch, the inner archway of the South porch and part of the west wall of the Nave are the only surviving parts of the Norman fabric.

A Bell Cote was added above the East wall of the Nave and the Chancel arch was strengthened (thickened) to take the weight. Before they were removed in 1930 (one is now at John Taylor of Loughborough, the bellfounders) they were listed as the only bells in the Diocese of Peterborough that had been cast before 1300.

The South arcade of the Nave has been rebuilt. A Chantry Chapel was added onto the North side of the Chancel. The North wall was replaced by an arcade and the North Aisle. The font dates from this period. The Chancel was rebuilt and the South porch added.

The windows date from the 14th century (the East window from 1330) as does the wooden door in the South porch.

During the 16th century a third Sanctus bell was in use.

Later the West end of the the North Aisle and the Chantry Chapel became derelict and part of the Nave was exposed to the weather. These were repaired and a stone in the west wall, dated 1680, records these repairs under the chuchwardens Robert West and John Holden. The South porch has a date stone of 1665. A pewter flagon bread holder and a silver chalice and paten are from this date, but for security reasons are no longer kept in the church.

There are tenders dated 1834 for building a new fire engine house in the Chapel yard together with a bill dated 1888 for 26 buckets, lettering, engine box lining and fastening, engine door and lettering for a cost of 8s 6d.

In 1877 a large Bible was given to the church by the rector of Paston when the first vicar of Werrington appointed. At this time the church was described as being “in a bad state of repair and the external appearance is not promising” (Historical and Architectural notes of 1859 and 1868). During the restoration that followed the Nave was restored and the West end of the North Aisle was demolished, repaired and a new arch provided. The roof was repaired, the floor raised, heating apparatus installed, the box pews and choir gallery removed and new seating added. During this reordering the font was moved to its present position. Despite the population being less than 1000 people the costs of about £1000 were met from the parish Church Restoration Fund. Cottages located just to the North of the church, in what is now the church yard, were demolished during this restoration. This date added to the stone in West wall recording 1680 repairs. Before 1884 the floor of the church was strewn on the Feast Day of St John the Baptist (24th June) with grass or hay from a local meadow (east of Car Dyke). The South porch has a date stone of 1892.

In the late 19th century the churchyard was extended on land given by Edward Peach. The Eastern end was marked by line of elm trees. Until this time churchyard did not extend North of the building. Cottages to the West of the church were demolished at about this time and the land taken into the churchyard. The earliest date on a memorial in churchyard is 1851. Prior to this most burials were probably in Paston. All burial records up to 1853 are kept at Paston church.

The Chancel was again restored in 1901/2 using original materials and the low side window was opened up. Two new bells, cast by John Taylor and Co., were used to replace the older bells. The churchyard was further extended in 1932 and new softwood pews were installed at this time. A new pipe organ was installed in 1975 and replaced by an electronic Johannus organ in1986.

In 2001 an extension was added to the north west corner of the church to provide toilet facilities and a new heating system was installed.
