English Heritage's best-known role is as the guardian of over 400 historical and archaeological sites, from Stonehenge to the world's earliest iron bridge. It has major responsibilities in conservation, giving advice, registering and protecting the historic environment. The properties are part of the portfolio of sites amassed by the British Government between the 1880s and the 1970s to form the national collection of built and archaeological heritage. As a superb new publication in Scala s popular Director's Choice series, Dr Simon Thurley, Chief Executive of English Heritage since 2002, offers us his personal selection from the hugely diverse properties in his care, giving a unique insight into their history and attractions.
