Then the first pair of rectangular two-storey porticus were added, either side of the east end of the nave. A second pair of porticus, west of the first, was added later. The second floor of the porch has two doorways, each with a semicircular arch. One is at the western end on the outside of the church. Over its arch are a square hood-mould with an animal's head above. This may have led to an outside gallery. The other is at the eastern end facing into the nave. It may have led to a gallery in the nave.
