Castel dell'Ovo 
Description
The oldest site of fortification in the city, today the castle structure is mostly from the 15th Century, however the rooms inside have been turned into a conference centre. You can't visit the rooms, but you can wander round the battlements and roofs where there are lovely views over the Bay of Naples, the city and off to Capri and the Sorrento Peninsular.
