Areni-1 cave, also known as "Bird Cave", is located in Areni village of Vayots Dzor province, on the shores of the Arpa River.The cave comprises a range of spaces, hewn in the rock, linked with narrow aisles. In the upper parts of the cliff it has several holes of fewer diameters. The exit is partially covered with large stones.
This cave belongs to clastocarstic caves, because it originated in limestone conglomerates. Since 2007 archaeological researches have been held here. As a result, materials dating back to 4200-3500 BC were found: plant residues, crockery, grape and apricot kernels, pieces of cloth, knitted of reed, women jewelry, part of the mummified goat body and so on.
In 2008 during the archaeological excavations the oldest shoe in the world was found in this cave. The shoe, filled with grass is for the right leg; it is rather small: 37 size according to the European standards. The laboratory studies showed that it has history of 5637-5387 years.
Several years ago a place, equipped for wine production was found in Bird Cave. This most ancient winery in the world has 5000-5500 year history.
