Valparaiso, Chile (2006)

Valparaíso (literally in Spanish: Valle Paraíso (Paradise Valley) and also called "Valpo" locally) is a city in central Chile and one of the country's most important seaports and an increasingly vital cultural center in the hemisphere's Pacific Southwest.

Valparaíso was declared a World Heritage Site in 2003, thanks to its historical importance, natural beauty (large number of hills surrounding a picturesque harbour), and unique architecture (particularly, a mix of 19th century styles of housing). Built upon dozens of steep hillsides overlooking the Pacific Ocean, Valparaíso boasts a labyrinth of streets and cobblestone alleyways, embodying a rich architectural and cultural legacy.
