CHRISTCHURCH, New Zealand, June 28 (Xinhua) -- The World Heritage Committee inscribed Thursday Teide National Park of Spain on UNESCO's World Heritage List.

Teide is of global importance in providing evidence of the geological processes that underpin the evolution of oceanic islands, complementing those of volcanic properties already on the World Heritage List, said the World Heritage Committee.

Situated on the island of Tenerife, Teide National Park covers 18,990 ha and features the Teide-Pico Viejo stratovolcano that, at 3, 718 m, is the highest peak in Spain.

Standing 7,500m above the ocean floor, it is regarded as the world's third tallest volcanic structure and is situated in a spectacular environment.

Spain is the country with the most World Heritage sites in the world, with now 42 sites, and the Italy (40) the second and China (35) the third.

The Committee continues its 31st annual meeting here to consider more nominations of the World heritage sites.

Over 600 international delegates attend the ten-day meeting starting Saturday. The conference over the last three days reviewed sites in danger, site management and protection.

In 1972, United Nations Educational, Scientific and Cultural Organization (UNESCO) adopted the World Heritage Convention as a way to encourage the identification, protection and preservation of the world's most outstanding cultural and natural heritage sites.

With 183 member countries and more than 830 sites, it is one of the most widely supported United Nations' conventions.
