Picturesque Valparaiso was one of the first Chilean cities founded by the Spanish. The city is an historic port and university town, famous for its labyrinth hills, which are covered in quaint, colorful old houses and accessible only by a steep climb or by the city's unique system of funicular railways. Through the efforts of the Chilean government emphasizing the city's culture, heritage preservation, and economic development via tourism, Valparaiso was bestowed designation as a World Heritage Site by UNESCO in 2003.
