Santa Severa Castle
Italy's most famous ghost resides here.
As in the real ghost stories, the dusky corridors of this ancient manor are filled with ominous footsteps and, under the cover of night, mystical images of the first owners of this ancient castle come to life.
Witnesses of these mysterious phenomena are numerous visitors to the 12th-century castle, as well as the working staff.
But the biggest surprise for the archaeologists was the ancient cemetery in the castle courtyard with more than 400 graves.
