14th-century star-shaped fortress 250 metres above the bay, with 360-degree views from Vesuvius to Capri. Military architecture at its most brutal. The ramparts are the best viewpoint in Naples — nothing else is close.

Walk the full perimeter of the star fortress — each bastion offers different angles. The view south over Chiaia and the bay is the postcard shot. Walk the inner courtyard and climb to the upper levels for Vesuvius framed by medieval stone. The adjacent Certosa di San Martino is worth combining if you have energy for museum interiors.
Late afternoon for golden light on the bay and Vesuvius. Sunset is spectacular but the fortress closes at dusk (check times). Morning for clearer air if you want island visibility. Take the funicular from Chiaia or Montesanto — the walk from below is steep and unrewarding.
Built in 1329 on the site of a 10th-century church, rebuilt in the 1530s into its current six-pointed star plan. Used as a military prison for centuries. The thick volcanic tuff walls and bastions were designed to withstand cannon fire. Napoli's best panorama — the city makes sense from here. Bring water. Minimal shade. The fortress is mostly empty inside (the museum collection is modest) but the architecture and views are the reason to visit.
