In consequence of the conflicting opinions entertained respecting the origin of the Circular Towers of Churches, I have been led to ascertain their proportional number in Norfolk; in order to illustrate, if possible, their origin. In doing which, I find that they are more frequent in those parts of Norfolk in which thick beds of diluvial gravel occur; particularly in Clavering hundred (the south-east angle of the County), where they equal in number the square towers: they are found also in the northern part of Suffolk under similar circumstances, and that they are but thinly distributed, or entirely absent, in other counties of England. Their dimensions are small, and many of them have been finished with an octangular top, of comparatively modern workmanship; they are all built with flint boulders, with the exception of that attached to the church of West Dereham, which is of Car-stone; and I have no hesitation in stating my conviction, that they owe their form, not to any peculiar style, but have been thus built from necessity, in consequence of the absence of freestone in the soil; and that the necessity originally influencing the Saxons, extended itself to the Normans, as may be seen in the towers of the parish churches of St. Paul and St. Mary in Norwich, founded after the Conquest.
