Crotone’s old town is built on the hill that was the acropolis of Greek Kroton, and its top is occupied by one of the largest fortresses in Calabria. A castle stood here from the 9th century, when the coast was exposed to Saracen raids. What you see now is mostly the work of the 1540s, when the Spanish viceroy Don Pedro de Toledo had it rebuilt for Emperor Charles V to withstand artillery and the Ottoman fleet.
The result is a huge irregular polygon of sloping walls and bastions, anchored by two round towers that survive from the earlier castle — the Torre Aiutante and the Torre Comandante. Much of the stone is said to have come from the ruins of ancient Kroton and from the temple at Capo Colonna.
Top things to do at Castle of Charles V
Walk the ramparts
When the interior is open, the wide terraces give the best views in the city: over the harbour, the roofs of the old town and south along the coast towards Capo Colonna.
Circle the walls from outside
Even with the gates closed, the walk around the base of the walls is worth it for the sheer scale of the masonry and the two round towers.
Check what is on
Parts of the castle have housed a small civic museum and are used for exhibitions and summer events. Access has varied in recent years because of restoration work, so ask at the tourist office or check locally.
How to get to Castle of Charles V
- On foot: from Piazza Pitagora walk up through the old town in about ten minutes, or approach from the harbour side along Via Risorgimento.
- By car: there is parking at the foot of the walls near the port.
Insider tips
- Opening of the interior is not guaranteed — plan to enjoy the exterior and treat a visit inside as a bonus.
- Late afternoon gives the best light on the walls and the coolest walk.
- The national archaeological museum is five minutes away; see them together.
