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. The square-headed south window of the “Fynderne Chapel” composed of four lights, with two rows of trefoil and quatrefoil tracery in its upper part, is worthy of notice as a good specimen of this style, and was probably inserted about the time of the completion of the tower and spire. The other windows in the church of one, two, three, and four lights, are very simple examples of this period, and, like the chancel arch, have very little pretensions to architectural merit, in design at least. The _Perpendicular Style_ is represented by the clerestory windows of two lights each, the roof of the church, and the south porch. The high-pitched roof of the earlier church was lowered—the pitch is still indicated by the string-course on the eastern face of the tower—the walls over the arcades were raised several feet from the string-course above the arches, and the present roof placed thereon. It is supported by eight tie-beams, with ornamented spandrels beneath, and wall pieces which rest on semi-circular corbels on the north side, and semi-octagonal corbels on the south side. The space above the tie-beams, and the principal rafters is filled with open work tracery. Between the beams the roof is divided into six squares with bosses of foliage at the intersections of the rafters. The south porch, with its high pitched roof, and vestry, belongs to this period. It had a window on either side, and was reached from the south aisle by a spiral staircase (see plan of church).
