A peculiarity of the church architecture is the use of flint for purposes of ornamentation, often of a very elaborate kind, especially on the porches and parapets of the towers. Another characteristic is the round towers, which are confined to East Anglia, but are considerably more numerous in Norfolk than in Suffolk, the principal being those of Little Saxham and Herringfleet, both good examples of Norman. It is questionable whether there are any remains of pre-Norman architecture in the county. The Decorated is well represented, but by far the greater proportion of the churches are Perpendicular Gothic, fine examples of which are so numerous that it is hard to select examples. But the church of Blythburgh in the east and the exquisite ornate building at Lavenham in the west may be noted as typical, while the church of Long Melford, another fine example, should be mentioned on account of its remarkable lady chapel.
