An abandoned Japanese island on which a James Bond movie was filmed, forgotten underground reservoirs in the heart of London, an entire town swallowed up by the sands of Namibia, an exceptional Tuscan castle deserted for decades, a grandiose cinema in disrepair in Tangiers, spectacular disused factories in the USA, Germany, and Hungary... Throughout the world, much of our architectural heritage is all too often forgotten. Many of the world's sleeping treasures are regarded as worthless relics of a bygone era. This outlook is only set to improve, as this atlas proves that in every corner of the globe, it's essential to contribute to safeguarding the heritage on which our world's cultural wealth is based.
