Had the chance to visit Cartagena and see the sights there. In the center are great monuments of Roman heritage as well as on the waterfront there is the naval shipyard of Navantia and a Naval museum with displays of the Spanish highlights as well as their first submarine. Very recommendable city to visit. Just outside the city is an informal settlement on naval land where people have erected "summer houses". The Navy tolerates them as long as they're not built further or any more land is occupied.
