The year 2013 marks the 50th anniversary of the establishment of diplomatic relations between Korea and Peru. The two countries have maintained close cooperative relations, as bilateral exchanges become more active recently in economics, culture, education and other areas. In celebration and commemoration of this 50th anniversary, Korea Post and its Peruvian counterpart issue a set of joint stamps featuring the UNESCO World Heritages located in each country - Korea's Seongsan Ilchulbong Peak and Peru's Machu Picchu.
Also called "sunrise peak", Seongsan Ilchulbong got its name "Seongsan" (castle on the mountain) since its towering mountaintop looks like a castle, and "Ilchulbong" (sunrise peak) since the sunrise seen from the mountaintop is such a splendid sight. Located on the eastern coast of Jeju, it is a classic tuff cone formed around 40,000 - 120,000 years ago by a hydro-volcanic eruption in the shallow water seabed. The highest point of the crater is 179 meters above the sea level, with the lowest point being 89 meters above the sea level and the diameter being 570 meters. Designated as a Natural Preserve Area, Seongsan Ilchulbong is home to 220 species of land animals and 330 species of marine plants. It was designated as the UNESCO World Natural Heritage in 2007.
Meaning "the old peak", Machu Picchu is the ancient city of the Inca Civilization, located on the 2,430m-high, isolated mountaintop of the Andes Mountains in Peru. Also called "the city in the air" since it can't be seen from the foot of the mountain, it was built around 1450 for Pachacuti, the emperor of the Inca empire. For unknown reasons, it was abandoned 100 years later only to be uncovered by Hiram Bingham, the explorer from the U.S. in 1911. Having once housed about 200 buildings such as temples and houses, together with the terraced fields and waterways, it shows the essence of the outstanding architectural and civil engineering technologies of the Inca Civilization that could handle huge stones quite freely. Machu Picchu was designated as a UNESCO Mixed Heritage site in 1983.
