The north aisle has three 15th-century windows of three lights with restored tracery, and north door to the west of them dating to 1826, in the north wall. This door opens to the north porch, which was substantially repaired and altered in 1826.Gray, pg 19 The west window of three lights has for the most part modern stonework, but a few old stones remain. The statue of the Virgin Mary with Child on the north wall was given to the church in memory of the Very Rev. Albert Victor Baillie, Dean of Windsor, who died in Baldock in 1955. The statue, by Sir William Reid Dick, had been presented to Baillie on his retirement from Windsor.Gray, pg 25
