A lovely park, inaugurated in 1888 by Austrian emperor Franz Joseph. The park is at the site of and named after a Turkish entrenchment ("Türken-Schanze") of the first Turkish siege on Vienna in 1529. It is close to the University of Agriculture, and features a variety of botanic rarities from all continents.
Vienna Technical Museum
This museum exhibits machines, transportations, electronic equipment, and the like from their first design up to their current form. The museum is huge at 22,000 m² and requires at least two hours to go through.
The indoor pool is 25 m long, and in summer the outdoor area offers a nice view over Vienna. The temperature of the pool varies according the week.
Built between 1927 and 1930 by the Otto Wagner's student Karl Ehn, the Karl Marx-Hof is a public housing complex (called "Gemeindebau" in Vienna), from the time of the social-democratic public housing programme during Austria's First Republic. With its 1382 Apartments and roughly 1,1 km in length, Marx-Hof is the world's longest contiguous public housing complex and probably Vienna's most famous "Gemeindebau". The permanent exhibit Red Vienna (in Wash House #2) is devoted to the history of Red Vienna, a period of one-party rule by the Social Democrats from 1919-1934. The non-exhibit parts of the building are still used as housing, so please respect the residents' privacy. Guided tours (German only) are offered on Sundays at 13:00, with no reservations required.
