Roman ruins sit under modern streets, and naval history mixes with tapas bars. Don't just look up – look down and around.
Introduction
Cartagena (car-ta-HEH-na) is a port city with over 2,000 years of history packed into a walkable centre.
Founded by the Carthaginians, then taken by the Romans, it's been a strategic naval base ever since. Today, you get Roman theatres next to modernist buildings and sailors' bars.
This guide is for spending one day here. We'll focus on what's actually worth your time.
What to see and do
Start at the Roman Theatre. It was buried under the city until 1988. The museum shows how they found it, then you walk out to the theatre itself. It's impressive because it's so well preserved.
Roman Theatre Museum
€6The entrance is on Plaza del Ayuntamiento. Buy a combined ticket with the Roman Forum district to save money. Allow 1.5 hours.
Walk up to the Concepción Castle. It's on a hill with views over the port. You can take a lift from the city centre up. The castle itself is a bit sparse, but the view is the point.
For naval history, the Naval Museum is free and shows Cartagena's role as a Spanish naval base. Submarine prototypes, old maps, and sailor stories. It's small but interesting.
Naval Museum
FreeNear the port. Closed on Mondays. Good for a quick visit – 45 minutes max.
Stroll along Calle Mayor. This pedestrian street has modernist buildings from the early 1900s, like the Casino. It's lined with shops and cafes. Good for people-watching.
Eat caldero. This is Cartagena's signature dish – rice cooked in a fish broth, served with alioli (garlic mayo). It's heavy, so share one portion between two people for lunch.
Restaurante Magoga
€€€They do a good caldero. Book ahead, especially at weekends. In the old town.
End at the port. Watch the boats, maybe have a drink at one of the terrace bars. The light at sunset is nice here.
Tips
The Roman Theatre and Roman Forum district have a joint ticket for €10. It's cheaper than buying separately. Both are worth seeing if you like ruins.
From June to September, it gets very hot. Do sightseeing in the morning or late afternoon. Wear a hat and carry water. Many places have air conditioning, but walking outside can be tough.
Say "car-ta-HEH-na" with the stress on the 'he'. Don't say it like the Colombian Cartagena (car-ta-HAY-na). Locals will appreciate it.
