The stunning remains of Spis is one of the largest castle sites in central Europe. The stone citadel of today began life in the 12th century and was once the home of the kings of Hungary before passing to a number of noble families. Even the stories of how Spis Castle came to be ruined are filled with legend with one claiming that the fire that broke out there in 1780 was caused by lightening, which hit soon after its last occupants left for good.
