successive building of the arcades to the aisles. Only the westernmost bay of the south wall remains, heavily rebuilt in the 15th century with a modern window. The floor has been tiled and is devoid of monuments. There is now no trace of a rood loft but Henry Larkin's will of 1471 left goods to pay for its maintenance. Against the tower wall the Dutch Sanctus bell used to hang (see Bells, below). A modern WC and kitchenette has been installed at the west end of the nave. The south aisle is separated from the nave by a three bay arcade. The arches are plainly moulded resting upon octagonal piers. The east window is modern, those in the side wall restored in the 15th century. A small piscina in the south wall gives evidence of the site of the Lady chapel. The floor has been raised and tiled so little other trace remains. A 1533 will refers to this: "To be buried in our Lady Chaunsell in the Church of Frennesbury. I give to the said church a cross to stand uppon the herse at buryings and obetts, and at other times uppon our lady aulter". At the west end of the south aisle, adjacent to the south door is the early 15th-century font. It is octagonal on a stone column with a modern wooden cover. There is a notable wall monument of 1621 to Thomas Buttler (see below) immediately behind it. The north aisle was built in 1883. The organ stood at the east end from 1987 until it was ruined, see below. The chancel is approached through a wide Norman arch. The squints on either side are modern. Malcolm Thurlby notes that the detailing of parts of the arch date it to around 1130. The chancel roof is in part original (notably the cross beams) but with much of the timberwork renewed. Traces have been found of the original windows in the side walls with surrounding frescos, but they were blocked in when the present Perpendicular windows were inserted. The rose window in the east wall is a reconstruction of the original when the wall was rebuilt. Below are three Norman windows which for many years had been covered by a reredos. When uncovered they here surrounded with medieval frescos, alas now fading. In the south wall there are the remains of a priest's door and a piscina.
