A hagioscope (or 'squint') is located in the North wall. There are various theories as to the purpose of these small windows but one can say for certain that they cast light on the secondary altar located on the North side of the church.
Originally, the nave had three large entrances: the existing entrances on the west and south sides (for the men) and the no-longer extant Northern entrance, traditionally for use by women. Men and women sat separately in the church. The Northern entrance has long been bricked up. Above this entrance on the outside can be found the lid of a sarcophagus on which can be seen a male figure in a devotional pose. When and why this was placed here is not known. However, we do know that behind it, a niche is located. In front of the sarcophagus, on the inside of the church, can be found a beautiful family pew.
