Book excerpt: The real-life answers to Italo Calvino’s Invisible Cities, Unruly Places explores the most extraordinary, off-grid, offbeat places on the planet. Alastair Bonnett’s tour of the planet’s most unlikely micro-nations, moving villages, secret cities, and no man’s lands shows us the modern world from surprising new vantage points, bound to inspire urban explorers, off-the-beaten-trail wanderers, and armchair travelers. He connects what we see on maps to what’s happening in the world by looking at the places that are hardest to pin down: inaccessible zones, improvised settlements, multiple cities sharing the same space. Consider Sealand, an abandoned gun platform off the English coast that a British citizen claimed as his own sovereign nation, issuing passports and making his wife a princess. Or Baarle, a patchwork city of Dutch and Flemish enclaves where crossing the street can involve traversing national borders. Or Sandy Island, which appeared on maps well into 2012 despite the fact it never existed. Illustrated with original maps and drawings, Unruly Places gives readers a new way of understanding the places we occupy.
