Just like ours at St Peter's. We have a stumpy tower through lack of money. The single bell is above the porch and the ropes feed down into the 'bell tower' the slim bit to the left of the front gate.

A lovely sunny day

Assume it was the original door into the nave (14th century) before the porch was built in the late 15th century. Window was probably to do with letting more light in. Only been stained glass since Victorian restoration and one of the windows in the north aisle was bricked in around the same time.
