Oetenbach nunnery

On 16 April 1986 Günther Tschanun opened fire in his workplace in Zürich, Switzerland, killing four people and seriously injuring one. The shooting came after difficulties and tensions in the building authority, where Tschanun was head. Tschanun escaped and was on the run for several weeks after the shooting, before he was caught in France. It was described by the Tages-Anzeiger as "one of the worst crimes in post-war Swiss history".Tschanun was initially sentenced to 17 years in prison in 1988 for four counts of intentional homicide. The case was sent to the supreme court, and in 1990 the sentence was overturned. Tschanun was instead sentenced to 20 years and found guilty of murder, and released on parole in 2000. He was issued a new name – Claudio Trentinaglia – which was only revealed to the public after he died in a bicycle accident in 2015.

Zürich ( ZURE-ik, ZOOR-ik, German: [ˈtsyːrɪç] (listen); see below) is the largest city in Switzerland and the capital of the canton of Zürich. It is located in north-central Switzerland, at the northwestern tip of Lake Zürich. As of January 2023 the municipality has 443,037 inhabitants, the urban area 1.315 million (2009), and the Zürich metropolitan area 1.83 million (2011). Zürich is a hub for railways, roads, and air traffic. Both Zurich Airport and Zürich's main railway station are the largest and busiest in the country. Permanently settled for over 2,000 years, Zürich was founded by the Romans, who called it Turicum. However, early settlements have been found dating back more than 6,400 years (although this only indicates human presence in the area and not the presence of a town that early). During the Middle Ages, Zürich gained the independent and privileged status of imperial immediacy and, in 1519, became a primary centre of the Protestant Reformation in Europe under the leadership of Huldrych Zwingli.The official language of Zürich is German, but the main spoken language is Zürich German, the local variant of the Alemannic Swiss German dialect. Many museums and art galleries can be found in the city, including the Swiss National Museum and Kunsthaus. Schauspielhaus Zürich is considered to be one of the most important theatres in the German-speaking world.Zürich is home to many financial institutions and banking companies.

Urania Sternwarte is a public observatory in the Lindenhof quarter of Zürich, Switzerland. Its name Urania refers to the muse of astronomy in Greek mythology.

The Lindenhof (lit.: courtyard of the lime) is a moraine hill and a public square in the historic center of Zürich, Switzerland. It is the site of the Roman and Carolingian era Kaiserpfalz around which the city has historically grown. The hilltop area—including its prehistoric, Roman, and medieval remains—is listed as a Swiss heritage site of national significance.

Turicum was a Gallo-Roman settlement at the lower end of Lake Zurich, and precursor of the city of Zürich. It was situated within the Roman province of Gallia Belgica (from AD 90 Germania Superior) and near the border to the province of Raetia; there was a tax-collecting point for goods traffic on the waterway Walensee–Obersee-Zürichsee–Limmat–Aare–Rhine.

The Lindenhof, in the old town of Zürich, Switzerland, is the historical site of the Roman castle, and the later Carolingian Kaiserpfalz. It is situated on Lindenhof hill, on the left side of the Limmat at the Schipfe.In 1747, a second-century Roman tombstone was discovered at the site, bearing the oldest attestation of Turīcum, the Roman-era name of Zürich, as STA[tio] TURIC[ensis], at the time a tax-collection point. The castle remained intact during the early phase of Alemannic immigration in between the fifth and sixth centuries, but was derelict by the ninth century, when it was rebuilt as a residence for Louis the German. It later became dilapidated and used as a source of building stone by the 13th century. The Lindenhof remained a place of civil assembly into modern times. In 1798, the citizens of Zürich swore the oath to the constitution of the Helvetic Republic on the Lindenhof. In 1851, the Modestia cum Libertate Masonic Lodge (established in 1771) bought the residence Zum Paradies and built a masonic building on the southern side of the square. In the early 21st century, it serves as a recreational space, a green oasis, and automobile-free zone in the old historic city centre. Its elevated position makes it a popular location for tourists to get an overview of the geography of old Zürich. In April, during the local holiday of Sechseläuten, the Lindenhof serves as the base of operations for whichever is the "guest canton" for that year.

The Hedwig Fountain (German: Hedwigbrunnen) or Lindenhof Fountain is a fountain in the Lindenhof hill in Zürich, Switzerland, which was built in 1912. The helmeted statue of a woman beside the fountain was made by Gustav Siber. It was built to honor the Zürich women, allegedly led by Hedwig ab Burghalden, who defended the city by duping the army of Duke Albert I of Germany during the siege of Zürich in 1292. They dressed in full battle gear in order to trick the Habsburg army into thinking that the city was well protected while their men were busy campaigning at Winterthur. The source of its water comes from the Limmat river.

Waisenhaus (also Amthaus I) is the last remaining building of the Oetenbach nunnery, and houses today the police department of the city of Zürich in Switzerland.
