Beyond its most familiar landmarks, Berlin, the Secret Atlas reveals a city shaped by contrasts, hidden details and unexpected places. From forgotten remnants of the Berlin Wall to a hidden sand dune, from an Expressionist church with a remarkable interior to a replica of the Palazzo Farnese, this atlas brings together a series of surprising and little-known sites. It also explores the remains of a former reception camp, a massive concrete structure used for soil testing, a cemetery chapel hosting light performances, and even a street that closes at night to protect beavers. Through these diverse and often overlooked locations, the book offers a different reading of Berlin, one that highlights its layered history, its constant transformation and its more discreet, lesser-seen spaces. Designed as a richly illustrated atlas, it provides a visual and engaging journey through the city, combining striking imagery with curated discoveries.
