The Stefaniewarte was built in 1887 as an observation tower on Vienna’s Kahlenberg.
The observation tower has two separate staircases.
Time had taken its toll on the building, making a general renovation unavoidable.
In coordination with the City of Vienna and the Federal Monuments Office, the control room was completely renovated so that it can be opened to the public.
The entire locksmith work was carried out by the company
Senft company.
