Linz in the context of "Klagenfurt"

Johannes Kepler (27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books Astronomia nova, Harmonice Mundi, and Epitome Astronomiae Copernicanae. The variety and impact of his work made Kepler one of the founders and fathers of modern astronomy, the scientific method, natural science, and modern science. He has been described as the "father of science fiction" for his novel Somnium.

Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He also taught mathematics in Linz, and was an adviser to General Wallenstein.

Upper Austria (German: Oberösterreich [ˈoːbɐˌ(ʔ)øːstɐraɪç] ; Bavarian: Obaöstareich; Czech: Horní Rakousy [ˈɦorɲiː ˈrakousɪ]) is one of the nine states of Austria. Its capital is Linz. Upper Austria borders Germany and the Czech Republic, as well as the other Austrian states of Lower Austria, Styria, and Salzburg. With an area of 11,982 km (4,626 sq mi) and 1.49 million inhabitants, Upper Austria is the fourth-largest Austrian state by land area and the third-largest by population.

Hurdling is the act of jumping over an obstacle at a high speed or in a sprint. In the early 19th century, hurdlers ran at and jumped over each hurdle (sometimes known as 'burgles'), landing on both feet and checking their forward motion. Today, the dominant step patterns are the 3-step for high hurdles, 7-step for low hurdles, and 15-step for intermediate hurdles. Hurdling is a highly specialized form of obstacle racing, and is part of the sport of athletics. In hurdling events, barriers known as hurdles are set at precisely measured heights and distances. Each athlete must pass over the hurdles; passing under or intentionally knocking over hurdles will result in disqualification.

Accidental knocking over of hurdles is not cause for disqualification, but the hurdles are weighted to make doing so disadvantageous. In 1902 Spalding equipment company sold the Foster Patent Safety Hurdle, a wood hurdle. In 1923 some of the wood hurdles weighed 16 lb (7.3 kg) each. Hurdle design improvements were made in 1935, when they developed the L-shaped hurdle. With this shape, the athlete could hit the hurdle and it will tip down, clearing the athlete's path. The most prominent hurdles events are 110m for men, 100m for women, and 400m (both sexes) – these three distances are all contested at the Summer Olympics and the World Athletics Championships. The two shorter distances take place on the straight of a running track, while the 400m version covers one whole lap of a standard oval track. Events over shorter distances are also commonly held at indoor track and field events, ranging from 50m hurdles upwards. Women historically competed in the 80m hurdles at the Olympics in the mid-20th century. Hurdles race are also part of combined events contests, including the decathlon and heptathlon.

Wilhering Abbey (German: Stift Wilhering) is a Cistercian monastery in Wilhering in Upper Austria, about 8 km (5 mi) from Linz. It was founded in 1146. The buildings, re-constructed in the 18th century, are known for their spectacular Rococo decoration.

Wels (German pronunciation: [vɛls] ; Central Bavarian: Wös) is a city in Upper Austria, on the Traun River near Linz. It is the county seat of Wels-Land, and with a population of 65,482 (January 2025), the eighth largest city in Austria.

Pargeting (or sometimes called Wall pargetting) is a decorative or waterproof plastering applied to building walls. The term, if not the practice, is particularly associated with the English counties of Suffolk and Essex. In the neighbouring county of Norfolk, the term "pinking" is used.

Patrick Leigh Fermor describes similar decorations on pre-World War II buildings in Linz, Austria. "Pargeted façades rose up, painted chocolate, green, purple, cream and blue. They were adorned with medallions in high relief and the stone and plaster scroll-work gave them a feeling of motion and flow."

The Alpine Foreland, less commonly called the Bavarian Foreland, Bavarian Plateau or Bavarian Alpine Foreland (German: Bayerisches Alpenvorland), refers to a triangular region of plateau and rolling foothills in Southern Germany, stretching from Lake Constance in the west to beyond Linz on the Danube in the east, with the Bavarian Alps forming its south boundary and the Danube its northern extent.

Mauthausen was a Nazi concentration camp on a hill above the market town of Mauthausen (roughly 20 kilometres (12 mi) east of Linz) in Upper Austria. It was the main camp of a group with nearly 100 further subcamps located throughout Austria and southern Germany.

The three Gusen concentration camps in and around the village of St. Georgen/Gusen, just a few kilometres from Mauthausen, held a significant proportion of prisoners within the camp complex, at times exceeding the number of prisoners at the Mauthausen main camp.
