Subsequent excavation cites evidence of there being a strongly defended univallate fort of late first Millennium BC.

The Roman fort was an outpost of the settlement at West Haddon and the Guilsborough encampment is believed to have been the work of Publius Ostorius Scapula, under the reign of Claudius.

A cell of Premonstratensian canons was founded at Kalendar or Kayland (on the border of Guilsborough and Cottesbrooke Parishes near Nortoft), probably soon after Sulby Abbey (c1155), and as it does not appear in the taxation of 1291, had probably ceased by then.

Large foundation stones have been dug up and the cell appears to have been moated (English Heritage Pastscapes 341939) and possible fishponds.

On 22 July 1612, four women and one man were hanged at Abington Gallows in Northampton for the crime of witchcraft, also known as the Northamptonshire Witch Trials.

They stood accused of bewitching a local noblewoman, Elizabeth Belcher (née Fisher) and her brother-in-law Master Avery and of killing, by sorcery, a child and numerous livestock.

[5][6][7] Although the hangings can be legitimately traced back to actual historic events, the story most commonly repeated is of less certain origins.

Her friends were thus apprehended riding on the back of a sow between Guilsborough and Ravensthorpe and were taken into custody and hanged, thus they were all reunited in death.

The problem with this story is that, although Agnes Brown remains a constant upon the pig's back, her companions swap names depending on the version being read.

This was a deep pool which stood off Cold Ashby Lane and was used by the local fire service as a water supply for many years.

The tower arch was closed about 1700 when a large gallery was erected in front of it to accommodate the boys from the grammar school.

An extensive restoration was carried out between the years 1815 and 1820, including the oak roof, preserving the bosses carved in wood illustrating the Seven Ages of Man.

Another extensive restoration of the Church took place in 1923 and 1924 when the Chancel was distempered, the roof repaired and the pillars and arches of the nave cleaned of plaster to show off the stone-work.

Fairly recently, a number of projects have taken place: conversion of the north porch into a toilet and kitchen; provision of a sound, audio and loop system; and, in celebration of the Queen's Golden Jubilee, external floodlighting.

The Rentons were also heavily involved in the local Women's Institute and were responsible for the tapestry of the witches in the village hall.

The secondary school, Guilsborough Academy, is on the edge of the village and takes children from 11 to 18, including a sixth form.
