The Indoor Terrace
The indoor terrace of the Danube Tower, formerly known as the Children's Terrace, is located at a height of 155 metres and offers a panoramic view of Vienna, protected from the weather.
This 14.20 metre level rests on 24 sturdy steel columns and was originally an open area with a handrail that allowed children to look into the distance on their own - but not directly downwards. To improve wind protection, the area was completely glazed in 2000, creating a two-storey interior.
The lower viewing terrace can be reached directly via the lift station at 150 metres. The indoor terrace can be reached via a staircase from the mezzanine level of the tower café, which runs around the tower shaft. From here, a further staircase leads down to the open viewing terrace.
Today, the indoor terrace not only serves as a wind-protected vantage point, but also as an exclusive event space. With its full-surface glazing, it has changed the appearance of the tower and is an indispensable part of the Danube Tower experience!

World record 100km June 2024
On June 10, 2024, Austrian ultrarunner Rainer Predl achieved a spectacular feat: 100 kilometers in 2,500 laps around the viewing platform of the Donauturm – completed in just 10 hours and 51 minutes.
The challenge began with a sprint up the 779 stairs to the 155-meter-high platform, where the actual record attempt took place. To avoid one-sided strain and dizziness, Predl changed his running direction every five kilometers.
He was supported by a five-person team, who kept his spirits high and provided refreshments. The event wasn’t just about athletic excellence – it was also a charity run. All proceeds went to the Sterntalerhof children’s hospice, an organization Predl has supported for years.
With this achievement, Predl clearly outpaced the previous record held by Markus Köhle, who completed the same distance in 12 hours and 45 minutes in Stuttgart in 2018.
The Donauturm run adds another unique chapter to Predl’s extreme running career – and he’s already planning his next challenge: the North Pole Marathon.
At the finish line, Predl smiled and said: “It was a fun story and a great experience – but I wouldn’t do it again!”
