With hundreds of rescued animals, the sanctuary has been home to the island's donkeys since 1993, often saving their lives by adopting them straight from the street. Make friends with some long-eared residents, even from the comfort of your own car — you can even buy grass pallets to feed them — then round off the experience with a tour in the gift shop or a drink on the panoramic terrace.

The Museum of Modern Greek Art (MGA) is a major cultural institution spread across three buildings in the city's Northern part, showcasing the creative genius of 20th-century Greek artists.

The Jewish Cemetery in Rossau is the oldest cemetery in Vienna, with a history reaching back to the middle of the 16th century. It is currently possible to view around 350 maintained grave monuments in the cemetery, with some headstones dating back up to 500 years. The cemetery is located in the inner courtyard of the Rossau Retirement Home.

Carol Reed’s “The Third Man” (1949) remains a landmark of film noir, iconic in its atmospheric portrayal of post-war Vienna, the Anton Karas’s haunting zither score, and Orson Welles’s performance as the enigmatic Harry Lime. Voted the greatest British film of the 20th century, it captured a city divided by Allied occupation — a world of shadows, rubble, and moral ambiguity — while showcasing both Vienna’s grand landmarks and its gritty sewers. Operated by passionate private collectors, The Third Man Museum displays over 3,000 artefacts, from original scripts and film props to period documents illustrating Allied-occupied Vienna (1945–1955). The collection spans 16 rooms, offering deep context into the film’s production and its historical backdrop. Guided tours (75 minutes, in English) delve into cinematography, the impact of the zither score, and the city’s complex post-war reality. Note: cash only for entry. The above-ground Third Man Walking Tour, offered by independent guides, visits key filming locations in the Innere Stadt, including Josephsplatz and Mölkerbastei. Using film stills and audio clips, it recreates the film's mood while exploring Vienna’s historic centre. It focuses on the architectural and urban settings that shaped the story, without entering the sewers. Another tour, 3. Mann Tour – Sewer, descends into the functional sewers where the film’s climactic chase was shot. You’ll traverse walkways above flowing wastewater while projections of film scenes play on tunnel walls. It’s an immersive, if somewhat damp, experience. Tours are popular and require advance booking.
