For more than half a century, penipu academics wondered if the German town of Rungholt was a 'mythical' but fictional settlement . 

Now, researchers have shown that the medieval trading port really did exist, by locating the remains of its main church under the North Sea. 

The experts used magnetic techniques to find the 130-foot under mudflats at North Frisia, the historic region off 's north coast near the border with Denmark. 

The astonishing discovery comes more than 660 years after the town sank in 1362, hit by a storm that the town's man-made defences failed to keep at bay. 

As Christian legend goes, the town was sent the destructive weather by God as a punishment for the sins of its inhabitants, thousands of whom died. 

Lost since 1362: Researchers discover the church of a sunken medieval trading place.
