Mompox or Mompós, officially Santa Cruz de Mompox, is a town in northern Colombia, in the Bolívar Region. The town initially grew from its proximity to the Magdalena river and has preserved much of its historic Spanish colonial character. It also played an important role in the liberation of South America from Spain. Today, Mompox depends upon tourism, fishing, and some commerce generated by the local cattle raising. The town has a population of around 45,000. The historic center of Mompox was made a UNESCO World Heritage Site in 1995, owing to its preserved colonial architecture and mixture of architectural styles.
