And UNESCO statement
According to UNESCO’s preliminary assessment on the ground, the monuments and sites within the Kathmandu Valley World Heritage property, as well as several other cultural and natural heritage sites located in the area, have been heavily affected. In particular, Durbar Squares of Patan, Hanuman Dhoka (Kathmandu) and Bhaktapur are almost fully destroyed.
Nepal’s natural heritage, in particular the World Heritage site of Sagarmatha National Park, including Mount Everest, has also been severely affected by the earthquake. Minimal impact has been found to the World heritage site of Lumbini, the Birthplace of the Lord Buddha (1997), and Chitwan National Park (1984). http://www.unesco.org/new/en/media-services/single-view/news/unesco_to_assess_the_imp act_on_nepals_cultural_heritage_of_the_devastating_earthquake/#.VT7al8uKC4Q
