Around the time of its founding in 1533, Cartagena was the principal port from which the Spanish Crown transported its greatest riches and so, it was necessary to construct extremely strong fortifications to repel attacks by pirates and would-be thieves. Constructed by the in stages, beginning in 1586, Las Murallas (the walls of the old city) are now the most comprehensive in South America and are one of the most well preserved ramparts in the world. The region has been declared a World Heritage Site by UNESCO.
The precincts of the wall also had the function of separating the rich people from the poor and the walls are complemented by fortresses on the coast and the fort of San Sebastian del Pastelillo and Fort San Fernando de Bocachica.
We recommend visiting this wonderful monument especially at dusk when you can watch the sunset and enjoy a romantic stroll atop the wall.
