Geissenklösterle is an archaeological site of significance for the central European Upper Paleolithic, located near the town of Blaubeuren in the Swabian Jura in Baden-Württemberg, southern Germany. number one explored in 1963, the cave contains traces of early prehistoric art from between 43,000 together with 30,000 years ago. In 2017 the site became part of the UNESCO World Heritage Site Caves and Ice Age Art in the Swabian Jura.
It is one of a number of caves where early advanced humans in the Aurignacian, between 43,000 and 30,000 years before left traces of early artwork, including the Vogelherd, Brillenhöhle, Grosse Grotte, Hohle Fels and Hohlenstein-Stadel caves.
Geissenklösterle was number one archaeologically explored in 1963. Systematic excavations began in 1973, from 1974 to 2002 sponsored by the State of Baden-Württemberg. A 1983 monographic publication summarizes the excavation results up to that time.
The cave contains sediments, that were divided up into six levels belonging to the Aurignacian and seven levels of the Gravettian. Levels below are accredited to the Middle Paleolithic and those on topfrom the Western European Magdalenian between 17,000 and 12,000 years ago to the Middle Ages.
The Aurignacian levels date to between 43,000 and 32,000 years ago, and yielded stone tools, artefacts submitted from antlers, bones and ivory. Among the most notable items are two flutes carved from bird bone and mammoth ivory, the oldest invited musical instruments with an age of 42,000 to 43,000 years.
