The Mannesmann Tower Vienna ( Mannesmann Tower, also called Messeturm ) was a 150 metres (490 ft) tall steel lattice tower with a triangular cross-section that was built in 1955 by the Mannesmann company on the exhibition grounds in Vienna. The Mannesmann tower was a gift from the Düsseldorf-based Mannesmann AG to the Vienna Trade Fair and was realized under the direction of Josef Fröhlich. It was built from seamless tubular steel. The manufacture of seamless steel tubes by rolling was a process developed by Mannesmann in 1885 and the term Mannesmann tube was synonymous with seamless steel tubes for many decades. Similar towers already existed in Düsseldorf (1954, 143 m), Sao Paulo (1954, 100 m) and other cities. During the night the tower was illuminated with neon lamps. A corner junction was specially exhibited at the foot so that the connection between the individual pipes could be seen. When Mannesmann exhibited at a trade fair in the 1950s and 1960s, it had its stand by this tower. It served the cellular and non-public mobile land radio service, including the radio of the medical emergency service. At the end of the 1950s, thought was given to erecting a meteorological measuring point on the tower in order to record ground inversions, as it protruded just above the level of the factory chimneys. Meteorological measuring stations were actually implemented and planned from the start at the Danube Tower. The tower was demolished in 1987.

The Vienna University of Economics and Business (German: Wirtschaftsuniversität Wien, WU) is a public research university in Vienna, Austria, the largest university focusing on business, management and economics in Europe. It has been ranked as one of the best business schools in Europe and received Triple accreditation (AACSB, EQUIS and AMBA). Vienna University of Economics and Business ranked 36th among more than 13,000 universities worldwide offering degrees in Business & Management in the 2022 QS World University Rankings by subject. Today, WU has more than 20,000 students and over 400 researchers and lecturers, among those about 90 full professors. It increasingly draws students from outside Austria, mostly from Central and Eastern Europe. Most of the faculty are of Austrian or German nationality.

Leopoldstadt (German pronunciation: [ˈleːopɔltˌʃtat] (listen); Bavarian: Leopoidstod, "Leopold-Town") is the 2nd municipal district of Vienna (German: 2. Bezirk) in Austria. As of 1 January 2016, there are 103,233 inhabitants over 19.27 km2 (7 sq mi). It is situated in the heart of the city and, together with Brigittenau (20th district), forms a large island surrounded by the Danube Canal and, to the north, the Danube. It is named after Leopold I, Holy Roman Emperor. Due to its relatively high percentage of Jewish inhabitants before the Holocaust (38.5 percent in 1923), Leopoldstadt gained the nickname Mazzesinsel ('Matzo Island'). This context was a significant aspect for the district twinning with the New York City borough Brooklyn in 2007.

The Prater Liliputbahn is a 381 mm (15 in) gauge light railway in Vienna, Austria. Opened in 1928, and extended in 1933, the railway operates primarily as a tourist attraction, but also provides transport links around the wider area of the Prater park, the amusement park (Wurstelprater), and the sports stadium. Although a year-round service was provided for many years, it is now more common for the railway to close during the months of December, January, and February. Originally steam-operated, the railway now uses a mixture of steam and diesel motive power. The railway can be reached by bus, tram, or metro from central Vienna, followed by a short walk, but following the extension of tram line 1, there is now an almost direct interchange with the Vienna tram network at the railway's Rotunda Station. The railway is named after the fictional island Lilliput (German: Lilliput and Liliput), inhabited by very small individuals in Gulliver's Travels (German: Gullivers Reisen) by Jonathan Swift.

Messe Wien (English: Trade Fair of Vienna) is the biggest trade fair in Austria and one of the most important economic factors of Vienna. This venue failed to win the bid for hosting the Eurovision Song Contest 2015, after Conchita Wurst won the final in 2014.

The Vienna Institute of Demography (VID) (until 2002: Institut für Demographie/IfD) is a research institute of the division for humanities and social sciences within the Austrian Academy of Sciences (ÖAW) and part of the three "pillar institutions" of the Wittgenstein Centre for Demography and Global Human Capital.

The Wittgenstein Centre for Demography and Global Human Capital (IIASA, VID/ÖAW, WU) is a research collaboration between the International Institute for Applied Systems Analysis in Laxenburg, the Vienna Institute of Demography of the Austrian Academy of Sciences, and the University of Vienna, both located in Vienna. From 2011-2019 the Vienna University of Economics and Business (WU) was the Centre's university pillar. The Centre was founded in 2010 by demographer Wolfgang Lutz who had won the Wittgenstein Award in the same year.The Wittgenstein-Preis, the highest Austrian science award, is given out by the Austrian Science Fund, and Lutz (who was the first social scientist to win it) used the 1.5 million euro prize money to establish the Centre by teaming up several existing demographic research institutions in and around Vienna which had been cooperating before but not under the umbrella of a common concern. These three pillar institutions – the World Population Program of the International Institute for Applied Systems Analysis (IIASA), the Vienna Institute of Demography of the Austrian Academy of Sciences (VID/ÖAW) as well as the Demography Group and the Research Institute on Human Capital and Development at the Vienna University of Economics and Business (WU) – each put a different emphasis and can therefore combine their strengths in the fields of demography, human capital formation and analysis of the returns to healthcare and education. The Centre’s objective is to provide a sound scientific basis for decision-making at various levels by better understanding the implications of changing population structures and human capital investments for the well-being of mankind under a global perspective. The Wittgenstein Centre is governed by founding director Wolfgang Lutz, Jesús Crespo Cuaresma (Director of Economic Analysis), Alexia Fürnkranz-Prskawetz (Director of Research Training) and Sergei Scherbov (Director of Demographic Analysis). Scientific advice and guidance is ensured by an International Scientific Advisory Board chaired by Sir Partha Dasgupta.There are some 60 researchers and 10 administrative staff members working at the Wittgenstein Centre in one of the three pillar institutions, two of which have been joined under a common roof since August 2015 when VID moved from its old premises in Vienna's 4th district to a new location on the WU campus in the 2nd district adjacent to the Vienna Prater: an additional campus building (D5) at Welthandelsplatz 2 now houses (on two levels) both the new Vienna Institute of Demography and the two relevant WU research groups next to each other, linked by the Demographenstiege (demographers' staircase). On 9 September 2015, the Centre celebrated its first five years, together with the 40th anniversaries of IIASA and VID, with a symposium on "Demography that Matters".

Wiener Looping is a steel roller coaster at Wurstelprater (located within Wiener Prater) in Leopoldstadt, Vienna, Austria. Built by Mack Rides, the coaster will span multiple sections of the amusement park and be one of its few attractions operated by owner Stefan Sittler-Koidl.

The coaster is planned to open in September 2024.
