East Anglia has a unique and very substantial heritage of flint-built churches and secular buildings over a wide area that range from Saxon times to the 20th century, many of them of exceptional beauty, and most in a good state of preservation. Stephen Hart considers that these buildings, in which a large number of different flintwork techniques and designs are used that are partly functional, partly dependent upon local materials, and partly aesthetic in inspiration, constitute an important part of our heritage. His book is the first comprehensive one to be written on English flint architecture and is likely to become the definitive work on the subject.
