The stone mushrooms of Beli Plast are just a little larger than your average shroom. The biggest is over three meters in height and they were formed thousands of years ago. They are made from lime stone which can be eroded by water. Over many centuries the water of a lake or a river can undercut limestone – and sometimes it can have bizarre results, especially when the water responsible for the erosion has disappeared. Alone like mushroom shaped islands it is little wonder that supernatural tales spring up around them.
