We're well into the 21st century but extraordinary archaeological finds spanning thousands of years continue to be unearthed across the British Isles. Some are discovered by amateur detectorists trying out their new toys, others by trained professionals following educated hunches or building on previous discoveries. Meanwhile, some are revealed by the ravages of global warming – by floods and heatwaves and other climate anomalies. These are the most interesting, impressive and surprising archaeological discoveries made in Britain in the last decade.
