Today I have three new-to-me UNESCO site cards, one from Wales, one from Spain, and one from Switzerland.
First is one of the cave paintings in the Altamira Cave in Spain. The paintings were made during the Upper Paleolithic, 18 to 14 thousand years ago. The caves were discovered in 1880, the first such discovery of prehistoric cave paintings. The cave was declared a UNESCO site in 1985.
Next is the Lavaux Vineyard landscape in Switzerland. People have been growing wine grapes on these terraces on the shores of Lake Geneva since the 11th century. The terraces are protected from development by the Swiss government, and since 2007 have been protected as a UNESCO World Heritage Site as well.
This card was sent by dannyozzy on the Postcrossing forum in late January, 2013.
And finally, the Pontcysyllte aqueduct in Wales. The aqueduct carries the Llangollen Canal over the River Dee Valley and is the longest and highest aqueduct in Britain. It is 307 meters (1,007 feet) long and 38 meters (126 feet) tall. The canal was completed in 1805 and listed as World Heritage Site in 2009.
Here are the stamps:
