Valparaíso is one of Chile’s most important seaports and an increasingly vital cultural center. The city is located in central Chile, where it is capital of the Region of Valparaíso. Although Santiago is Chile's official capital, Valparaiso houses the National Congress. 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. Valparaíso is protected as a UNESCO World Heritage Site and is often considered to be one of Latin America’s most intriguing urban areas. Valparaiso like most of Chile is vulnerable to earthquakes. The last major earthquake to strike the city directly was in 1906 which devastated the city and killed nearly 20,000 people.
