Caves and Ice Age Art in the Swabian Jura

The small Sirgenstein Cave, German: Sirgensteinhöhle is situated 565 m (1,854 ft) above sea level inside the 20 m (66 ft) high Sirgenstein, a limestone rock. The cave sits 35 m (115 ft) above the Ach River valley bottom in the central Swabian Jura, southern Germany. Archaeologist R. R. Schmidt excavated the site in 1906 during which he identified indices of prehistoric human presence. He recorded the complete stratigraphic sequence of Palaeolithic and Neolithic origin. In his 1910 analysis Schmidt inspired future archaeologists with his pioneering concept of including the excavation site within its geographic region, contextualizing it within a wide scientific spectrum and demonstrated valuable results as he correlated the Sirgenstein layer structure to those of prehistoric sites in France. Mammoth ivory beads dating from 39,000 to 35,000 years ago have been uncovered at the cave. Because of its historical and cultural significance and its testimony to the development of Paleolithic art, the cave was inscribed on the UNESCO World Heritage List as part of the Caves and Ice Age Art in the Swabian Jura site in 2017.

Sirgenstein Castle (German: Burgrest Sirgenstein) is a ruined castle on rock, over twenty metres high, with a cave inhabited in the Stone Age, the Sirgenstein, between the town of Blaubeuren and hamlet of Schelklingen in Alb-Donau-Kreis in Baden-Württemberg. The rock castle was probably built in the 13th century. Today its visible remains include castle walls, rusticated ashlar blocks and a neck ditch.

Geissenklösterle (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. First explored in 1963, the cave contains traces of early prehistoric art from between 43,000 and 30,000 years ago, including some of the oldest-known musical instruments and several animal figurines. Because of the historical and cultural importance of these findings, in 2017 the site became part of the UNESCO World Heritage Site Caves and Ice Age Art in the Swabian Jura.

The Hohle Fels (German pronunciation: [ˈhoːləˈfɛls]; also Hohlefels, Hohler Fels, German for "hollow rock") is a cave in the Swabian Jura of Germany that has yielded a number of important archaeological finds dating from the Upper Paleolithic. Artifacts found in the cave represent some of the earliest examples of prehistoric art and musical instruments ever discovered. The cave is just outside the town of Schelklingen in the state of Baden-Württemberg, near Ulm. Because of the outstanding archeological finds and their cultural significance, in 2017 the site became part of the UNESCO World Heritage Site Caves and Ice Age Art in the Swabian Jura.

The Brillenhöhle (German: Brillenhöhle, literally spectacles cave) is a cave ruin, located 16 km (9.94 mi) west of Ulm on the Swabian Alb in south-western Germany, where archaeological excavations have documented human habitation since as early as 30,000 years ago. Excavated by Gustav Riek from 1955 to 1963, the cave's Upper Paleolithic layers contain a sequence of Aurignacian, Gravettian and Magdalenian artifacts. In 1956 the first human fossils were discovered within a fireplace in the center of the cave, a discovery which made important contributions to the foundational understanding of the Magdalenian culture of central Europe.

The Blau (German pronunciation: [ˈblaʊ]) is a 22-kilometre-long (14 mi) river in Baden-Württemberg, southern Germany, and a left tributary of the Danube. The source of the Blau is the karst spring of Blautopf, in the town Blaubeuren, in the Swabian Jura. It flows east through Blaustein to the city of Ulm, where it empties into the Danube.

Blaubeuren (German pronunciation: [ˌblaʊ̯ˈbɔʏʁən]) is a town in the district of Alb-Donau near Ulm in Baden-Württemberg, Germany. As of December 2007 it had 11,963 inhabitants.

Blaubeuren Abbey (German: Kloster Blaubeuren) was a Benedictine monastery until the Reformation, located in Blaubeuren, Baden-Württemberg, Germany. It is now a Protestant seminary.

The Blautopf (German for Blue pot) is a spring that serves as the source of the river Blau in the karst landscape on the Swabian Jura's southern edge. It is located in Blaubeuren, Alb-Donau-Kreis, Baden-Württemberg, Germany (approximately 16 km (9.9 mi) west of Ulm).

The Blauhöhle is the largest cave system in the Swabian Alps in southern Germany. The Blauhöhle presumably originated in a time when the Danube still flowed through the Blau valley. Since the shifting of the Danube, several small rivers, the Schmiech, the Ach, and the Blau, have flowed through this valley. The cave system begins about 21 meters under water at the base of the Blautopf. It continues west and northwest, rising and falling several times until after a horizontal distance of about 1,200 metres (3,900 ft) it comes above the level of ground water and opens into the second big air-filled chamber. The maximum depth of the cave under water is 42 metres (138 ft). This chamber was first discovered in 1985 by Jochen Hasenmayer, who named it Mörikedom (Mörike Cathedral, named after Eduard Mörike). Hasenmayer's diving accident in the Wolfgangsee resulted in a long break in its exploration. For several years the cave has been explored by the Arbeitsgemeinschaft Blautopf (Blautopf Study Group, or Consortium), a team of cave divers from several different regional groups. This group has made progress exploring the cave, including making exact measurements of the way to the Mörikedom. The improvement of underwater breathing technology, especially the rebreather, has allowed for longer dives carrying less weight. The discovery of the Wolkenschloss (Castle of Clouds), another large, air-filled cavern, and the so-called Landweg (land-way), a long, open cave river behind the Mörikedom, were great successes for the Arbeitsgemeinschaft. Hasenmayer continued his attempts to explore the cave system in his cave submarine, Speleonaut. Since 2002 the Arbeitsgemeinschaft Höhle und Karst Grabenstetten (Cave and Karst Consortium of Grabenstetten), as a part of their work on a neighboring cave system, the Vetterhöhle, have attempted to dig a dry entrance into the Blauhöhle. In 2006 several large caverns were discovered in the Vetterhöhle, and in the autumn a connection was discovered between the Vetterhöhle and the Wolkenschloss. Also in the autumn of 2006, the Arbeitsgemeinschaft Blautopf discovered an enormous cavern at the end of the Landweg, measuring 170 m (560 ft) long by 50 m (160 ft) wide by 50 m high, which was named Apokalypse. The groups are now also working with yet another Arbeitsgemeinschaft on a sinkhole north of Blaubeuren, which is believed to be connected with the Blauhöhle behind the Apokalypse.

The Ach, also called Aach, is a river located in Baden-Württemberg, Germany. It flows into the Blau in Blaubeuren.

Schelklingen is a town in the district of Alb-Donau in Baden-Württemberg in Germany. It is situated 10 km north of Ehingen, and 20 km west of Ulm. Schelklingen and 82% of its territory form part of the Swabian Jura Biosphere Reserve.
