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.

Kaiser Franz Joseph-Bad
The swimming pool is 25 m long and has a retractable glass roof. It was built between 1912 and 1914. The bath offers a sauna and massage too.
A beautiful little theatre, mostly frequented by Viennese.
Grinzinger Pfarrkirche
Built in the 15th century, the church was burned in 1529 and 1683, during the first and second Turkish sieges of Vienna, and severely damaged during World War II. However one treasure did survive: the organ, on which both Beethoven and Schubert used to perform. The organ was modified several times since then and had fallen into severe disrepair, but in 1997 it was completely restored by a master organ builder and is now again played regularly.
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.
Haus des Heiligenstädter Testaments / Beethoven House
One of Beethoven's many residences within the city. While living here he composed his Symphony No. 2 in D major (Op. 36), as well as several other works.
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.
