Geisenklösterle is a cave near Blaubeuren and an important site for the European Upper Paleolithic. It is one of a number of caves where early modern humans in the Aurignacian, between 43,000 and 30,000 years ago left traces of early artwork. Geisenklösterle was first archaeologically explored in 1963. Systematic excavations began in 1973, from 1974 to 2002 sponsored by the land of Baden-Württemberg. A 1983 monographical publication summarized the results up to that time.
The cave has six levels belonging to the Aurignacian and seven levels of the Gravettian, besides earlier levels belonging to the Middle Paleolithic and later ones spanning the Magdalenian down to the Middle Ages. The Aurignacian levels date to between 43,000 and 32,000 years ago, and yielded stone tools, artefacts made from antlers, bones and ivory. Among the most notable items are a sculpture of a flutes of bird bone and mammoth ivory, the oldest known musical instruments with an age of 42,000 to 43,000 years.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
