Müllverbrennungsanlage Spittelau
A waste incinerator may not be the usual item to attract a visitor's attention, but after the Viennese painter/architect Friedensreich Hundertwasser restyled the plant's façade in 1989 (following a fire in 1987), it has become a surprisingly photogenic fixture in the cityscape. Guided tours are offered (in German only) for visitors wanting to gain more insight into Vienna's waste, recycling, and disposal systems; however it is possible to appreciate the exterior of the plant from many locations in the city.
Franz Schubert was born in a small apartment in this house in 1797. The museum, just like the apartment itself, is rather small and not wheelchair accessible. The top floor displays documents relating to the composer's life and work, while other rooms display paintings by the Austrian writer Adalbert Stifter.
Jüdischer Friedhof Rossau / Seegasse Jewish Cemetery
Vienna's oldest preserved Jewish cemetery, in use from the 16th century until 1784. In 1941 Nazi officials decided to raze the cemetery; in response a number of Viennese Jews removed 931 gravestones and buried them at the Zentralfriedhof. In the 1980s 280 of the gravestones were rediscovered and returned to their original locations. The cemetery was resanctified in 1984. Due to ongoing restoration work (as of late 2016) the cemetery cannot be entered, but can be easily viewed from an elevated walkway overlooking the site.
