ANCIENT UNDERGROUND CITY IN SPAIN
Edith Breeden has ported to me from California that in the early 1970s she and her husband were visiting Spain. They were taken to a site that had been "discovered" by a teenager from Rota, Spain, and he offered to show it to them.
She recalls, "I had never seen anything like it before - or since. Located near the town of Jerez de la Frontera on property belonging to a private company was an underground city.
It was entered by a large opening much like the mouth of a cave. Some poor people appeared to be camping there. We were led by the young man inside to what he said was the top floor of a 3-floor city (area).
"We did not venture any further, knowing he and his teenager friends had been lost in there for 3 days before finding their way out.
"We heard the area was to be flooded in order to keep others from going in - to prevent accidents. But leaving Spain, we don't actually know what was done."
