World HeritageSouth West England is blessed with four unique UNESCO World Heritage Sites. These are outstanding cultural and natural sites which illustrate the common heritage of mankind. They are ours to share, to cherish and to respect. Countries signed up to the World Heritage Convention make an international commitment to safeguard these sites for future generations. You can do your bit to help protect them by using 'green transport' - leaving your car behind and reducing traffic congestion and pollution."
