Round Tower Churches Society

'Churches with round towers are unusual ... There are 186 in England including those in a semi-ruinous condition and visible remnants of fallen towers. All are in East Anglia except for three in Sussex and two in Berkshire. Norfolk has 124, Suffolk 38, Essex seven and two in Cambridgeshire ... Some round tower church ruins could be included too, possibly adding seven in Norfolk and three in Suffolk. Most are medieval, dating from the 11th to the 14th centuries. Some pre-date the Norman Conquest.'
