On the banks of the Río Magdalena, Mompox is one of the most charming colonial towns in the Caribbean region. This former inland port was founded circa 1540. It was a port of call for boats transporting gold and silver from Ecuador to Cartagena, and the town grew in staggering fashion in the colonial era. It gradually receded into oblivion with the silting up of the river. Its remote location means that its colonial architecture has remained intact; it is designated a UNESCO World Heritage Site.
