The recess on the east end was destroyed when a flight of stone steps was made leading down to the crypt. These steps (there are six of them) are single, roughly made stones of varied length, resting on the earth, without mortar. When the flight was complete there would have been twelve, reaching from the top to the level of the crypt floor.

The steps would afford an easier and quicker approach to the crypt and church, but when they were made cannot now be said.

The recess on the north side was also destroyed when the outer stairway, and door, were placed there, probably, as before stated, in the thirteenth century. On the outside surface of the three walls, above the ground level, are still to be seen traces of the old triangular-shaped roofs which covered the three recesses, and served as buttresses to the walls. Similar “triangular arches” are to be seen at Barnack, and Brigstock.

The eastern end of the north aisle is the only portion of the ancient transepts above the ground level. During the restorations in 1886 the foundations of the Anglo-Saxon nave were laid bare, they extend westward up to and include the base of the second pier; the return of the west-end walls was also discovered, extending about four feet inwards.

Over the chancel arch the removal of many coats of whitewash revealed an opening, with jambs consisting of long and short work; a similar opening to the north of it used to exist, it is now blocked up.

The Early English Style is only represented by foundations laid bare during the restoration in 1885, and now indicated in the north and south aisles, by parallel lines of the wooden blocks, with which the church is paved. In the south aisle the foundations of a south door were also discovered (see plan of church). To this period belong the windows in the north side of the chancel, and in the narrow piece of wall between the last arch and chancel wall on the north side of the present choir. There were two corresponding windows on the south side, one of which remains. All these windows have been blocked up.

The Decorated Style is represented in the nave by four out of the six lofty pointed arches, supported by hexagonal columns; the two, on either side, at the east end of the nave, were erected in the year 1854.

The tower and steeple were finished in the year 1340. Basano, in his Church Notes, records the fact—“Anᵒ 1320 ?40. The tower steeple belonging to the Prior’s Church of this town was finished and built up, as appears by a Scrole in Lead, having on it these words—“Turris adaptatur qua traiectū decoratur. M c ter xx bis. Testu Palini Johis.”

A groined roof of stone, having a central aperture, through which the bells can be raised and lowered, separates the lower part of the tower from the belfry.

The north and south aisles were extended to the present width. The eastern end of the south aisle was also enlarged several feet to the south and east, and formed a chapel or chantry, as some say, for the Fyndernes, who were at one time Lords of the Repton Manor. A similar, but smaller, chapel was at the east end of the north aisle, and belonged to the Thacker family. They were known as the “Sleepy Quire,” and the “Thacker’s Quire.” Up to the year 1792 they were separated by walls (which had probably taken the place of carved screens of wood) in order to make them more comfortable, and less draughty! These walls were removed in 1792, when “a restoration” took place.
