This eerie real-life Atlantis has reappeared from under flood waters after spending 25 years submerged. Some 1,500 residents barely had time to grab their belongings when the spa resort of Villa Epecuen was swamped after a lagoon burst its banks in 1985. By 1993 the town, in eastern Argentina, which drew 20,000 visitors a year, lay hidden beneath 10 metres of water. But now, as the salty lagoon water recedes, spooky silvery ruins have re-emerged.
