Head south for about 25kms and you will come to Spain’s oldest port. Cartagena is one of Spain’s oldest cities, and still of major maritime importance to Spain, both commercially and militarily. A multitude of civilisations have left their mark on the city as numerous archaeological sites and museums will testify. In the heart of the city is a modern shopping area, which spills down past the tapas bars to the recently revitalised harbour. Here you will find the World’s oldest submarine on display, built in 1884 by a local man Isaac Peral.
