When the Roman legions could no longer successfully defend the borders of the Empire, and its territory was prey to raids and invasions by foreign peoples and armies, there arose the need for a new form of defence. Thus were castles born, along with the development of feudalism and the era now known as the Middle Ages.
A powerful and magnificent call to action to protect Earth and our legacy. War, climate change, natural disasters, and our own destructive behavior have endangered some of Earth's most precious treasures, from historical sites and monuments to unique natural habitats. This profusely illustrated volume pays tribute to some of the wonders that remain at risk, including the archeological remains of Afghanistan's Bamiyan Valley, devastated by the Taliban; Alaska's Denali National Park, harmed by tourism and uncontrolled development; Tanzania's Telous Game Reserve, victimized by poachers; and the Kiribati Archipelago in Oceania, which could vanish entirely due to rising sea levels. Places to Visit Before They Disappear captures a troubling present, offers a message of hope for the future, and calls on us all to protect our natural environment and cultural heritage.
30 years ago, UNESCO adopted the convention for the protection of the World cultural and natural heritage, which more than 150 countries signed. This book celebrates the success of the project, bringing the 300 most interesting architectural, natural and archaeological sites together.
