Some of the earliest recorded windmills were built in Suffolk, and since the middle ages Suffolk has been a county where windmills predominated. In the 1830s there were over 430 windmills in the county, though the advent of steam and oil engines and roller mills meant there was a rapid decline in numbers later in the nineteenth century. This survey lists all the surviving mills and mill remains. It also explains the technicalities of how the different types of mill worked, emphasising the particular local types and developments; and describes the life of the millers and the work of the millwrights. There is also an account of the restoration work which has been undertaken on them. Fully illustrated with photographs of what can still be seen today.
