I've only received mail twice this week but i still have lots of cards to upload and show here.
Lilia sent me another one of my UNESCO missing sites. Rio Abiseo National Park was created in 1983 to protect the fauna and flora of the rainforests that are characteristic to that region of the Andes, and was added to the WHS list in 1990.
The park is also home to over 30 pre-Columbian archaeological sites, being Gran Pajatén the most famous of them.

Gran Pajatén sits on a hilltop, and consists of a series of at least 26 circular stone structures atop numerous terraces and stairways. The ruins occupy an area of about 20,000 m². The principal buildings are decorated with slate mosaics displaying human, bird and geometric motifs. Analysis of ceramic samples and radiocarbon dates show that the area was occupied as early as 200 BCE, but the visible building ruins on the present site were constructed during Inca times. Based primarily on architectural evidence, the settlement is attributed to the Chachapoyas culture. - in: wikipedia
