Parque nacional del Teide
In celebration of the 50th anniversary of its transformation into a national park, in 2002 the paperwork was begun to declare the park a UNESCO World Heritage Site. On June 28, 2007, after five years of work and effort, UNESCO decided to declare the Teide National Park, World Heritage Site in the World Heritage Convention of UNESCO held in Christchurch, New Zealand. Teide National Park is also at the end of 2007, one of the 12 Treasures of Spain.
