Port, Fortresses and Group of Monuments, Cartagena
Situated in a bay in the Caribbean Sea, Cartagena has the
most extensive fortifications in South America. A system of zones
divides the city into three neighbourhoods: San Pedro, with the
cathedral and many Andalusian-style palaces; San Diego, where merchants
and the middle class lived; and Gethsemani, the 'popular quarter'.
