A superb find in Gaeta. A deep history of warfare and then served as a prison. Housed infamous Nazi war criminals. The tour includes the different cells used from the beginning until 1990. Epic views from the roof into the interior prison courtyard and overlooking the coast of Gaeta. English and Italian tours available for 10€. Great tour guide that was a wealth of knowledge. Parking on site but I recommend parking on the waterfront and walking up to the castle. Great views all along. read more
