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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
