Baku Flame Towers

The Baku Flame Towers are a striking and new element in the Baku skyline. Inspired by Azerbaijan’s long history of fire worship, the towers are an eternal flame for modern Baku. Located on the Caspian Sea in Azerbaijan, the site is perched on a hill overlooking Baku Bay and the old city centre. Werner Sobek was responsible for the facade engineering, parts of the structural engineering and construction supervision for this fascinating project.

The basic external geometry of all three towers is identical. However, they protrude to different extents above the respective building ground. Their heights are approx. 140 m, 160 m and 170 m respectively. From the very beginning, only an element facade was considered as a system for the building envelope. Here, the individual favade elements, including glass, can be prefabricated in the workshop and mounted directly on the building structure at the construction site.

Three Towers on a Common Podium

The project, with a site area of approx. 28,000 m², consists of three towers standing on a common podium. While the main supporting structures of the towers were conventionally constructed of concrete, the large-scale special uses on the top floors of the towers required filigree steel structures.

The total built-up area of the project is 245,000 m². At the base of the towers, they are connected by a glass roof. Underneath is a large shopping mall.
