Six white concrete domes stood on stilts off the southwest Florida coast, a solar-powered home built in the early 1980s by a retired oilman. Erosion left them in the open sea, and in 2017 and 2022 the hurricanes brought them down. They now lie under the Gulf.
In a bowl of desert outside Albuquerque stands a wooden structure as tall as a twelve-storey building, built almost without metal so that a B-52 could be parked on it and hit with a simulated nuclear pulse. It was shut down at the end of the Cold War, and it is still there.
In the Nevada desert the US government built two small American towns, filled them with furniture, food and dressed mannequins, and then dropped atomic bombs on them to show what would happen to a family at home. One was destroyed in 1953. Part of the other still stands.
Bakić's 37-metre monument to the 1941 uprising once glittered with Swedish stainless steel above the forests of central Croatia. Now it is stripped, graffitied and carrying phone antennas, and a Netflix crew has filmed in it.
In December 1943 the 150 people of Imber were told to leave their Wiltshire village for a few months so American troops could train there. They never came back, and the village still stands empty inside an army firing range.
Kadykchan in Russia's far north-east was dug out of the permafrost by Gulag prisoners in 1943 to feed a power station. Then a mine explosion and a state decision left its flats empty and its streets silent.
Prora was meant to be a seaside holiday camp for 20,000 workers, a block of concrete 4.5 kilometres long on Rügen's Baltic coast. The war stopped it before a single holidaymaker arrived, and the shell went on to serve three armies before the luxury flats moved in.
In 1997 a 45-metre Gulliver was laid out on a hillside below Mount Fuji, tied down by Lilliputians, and four years later the park was dead. The bank behind it had collapsed, and the giant stayed where he lay for six more years.
Cut into a mountain beside a narrow Crimean bay, Balaklava's secret submarine base was built to survive a nuclear strike and is now a museum.
Built in the Second World War with a runway half as long again as normal, RAF Sculthorpe became one of the biggest US Air Force bases in Britain, home to nuclear-capable bombers until it closed in 1992.
