Independent information website about the Berlin TV Tower
The Berlin TV Tower combines broadcasting technology, panoramic views, gastronomy and urban representation within a single structure. Built between 1965 and 1969 in the centre of East Berlin, it was designed from the outset as both a functional building and a highly visible landmark of the GDR capital’s urban planning. The political and historical background is explained in detail in the history of the Berlin TV Tower.
Its exterior form is defined by three elements: the reinforced-concrete shaft, which tapers towards the top; the spherical, multi-storey structure at a height of around 200 metres; and the antenna mast rising above it. Alongside technical facilities, the tower sphere houses the observation deck and revolving restaurant.
The protected ensemble includes the tower itself, the low-rise pavilion buildings around its base and the surrounding landscaped areas with flower beds, water cascades and greenery.
Overview
Berlin TV Tower architecture at a glance
The Berlin TV Tower was built as a television and radio broadcasting tower and as an urban landmark in the redesigned centre of East Berlin. Its reinforced-concrete shaft supports a 32-metre sphere containing seven floors. Above it is the antenna mast, which brings the structure to its present height of 368.03 metres.
The sphere was not constructed entirely at height. Its supporting steel framework was first preassembled at ground level, then dismantled into sections and lifted by crane onto the supporting platform at the top of the shaft.

Design and disputed authorship
The design of the Berlin TV Tower cannot be attributed conclusively to a single person. As early as 1959, Hermann Henselmann developed an important preliminary concept with his unrealised “Tower of Signals”. The design featured a slender tower crowned by a sphere and influenced subsequent plans for Berlin’s city centre.
Contemporary specialist publications named Fritz Dieter and Günter Franke as the designers of the tower that was eventually built. Hermann Henselmann was listed as an artistic adviser, although he considered himself the author of the overall design. Gerhard Kosel, who was temporarily responsible for the project’s overall management, also later claimed a major role in its authorship.
The TV Tower should therefore not be presented as the work of a single architect. It emerged from a complex planning process involving architects, structural engineers, specialist planners and government institutions. The Berlin State Heritage Office explicitly describes its precise authorship as disputed.
Construction of the Berlin TV Tower from 1965 to 1969
Work on the foundation began in August 1965. Concreting of the tower base started in March 1966, followed by work on the shaft. The 100-metre mark had already been reached by October 1966, and the reinforced-concrete shaft attained its final height of 248.78 metres in June 1967.
Construction of the tower sphere was prepared at the same time. Its steel framework was initially assembled on a trial basis at ground level. The individual components were then lifted by crane to a height of around 200 metres and installed on the ring-shaped supporting platform. Interior work began after the sphere and antenna mast had been completed.
The TV Tower entered service in October 1969. Its original height was approximately 365 metres. Modifications to the antenna system in 1997 increased its total height to 368.03 metres.
Foundation and reinforced-concrete shaft
The TV Tower stands on a ring-shaped foundation with an external diameter of around 42 metres. The load-bearing gravel and sand layers at the site allowed the foundation to be relatively shallow in relation to the height of the structure. Depending on the section, it extends approximately 2.70 to 5.80 metres into the ground.
The 248.78-metre reinforced-concrete shaft rises above the foundation. Its diameter decreases from approximately 16 metres near the bottom to around 9 metres at the top. This tapering reduces the structure’s weight and gives the tower its slender silhouette.
The shaft was constructed using a climbing-formwork method. The internal steel framework advanced slightly ahead of the outer concrete shell. The interior contains the lifts, utility lines, cable shafts and emergency staircase, among other facilities.
The concrete shaft weighs approximately 26,000 tonnes. Around 8,000 cubic metres of concrete were used in its construction.
Assembly and structure of the tower sphere
The tower sphere is the defining architectural element of the Berlin TV Tower. It has a diameter of 32 metres and contains seven floors. These accommodate visitor areas, technical installations and facilities used for television and radio broadcasting.
The engineers could not place the sphere on the shaft as a single enclosed component. Its supporting steel framework was therefore first preassembled at ground level. It was then dismantled into separate sections, lifted by crane onto the supporting platform and reassembled there.
The exterior shell consists of trapezoidal stainless-steel panels formed into pyramid-like elements. This faceted surface visually structures the sphere and produces different reflections depending on the light and viewing angle.
Further close-up images of the sphere, shaft and façade details can be found under Images and impressions of the Berlin TV Tower.
Observation deck, restaurant and technical floors
The publicly accessible levels are located in the lower part of the tower sphere. The observation deck is situated at a height of approximately 203.78 metres and has a diameter of around 24 metres. Above it, at roughly 207.53 metres, is the revolving restaurant SPHERE Tim Raue, whose floor has a larger diameter.
Additional floors above the visitor areas contain technical equipment for television and radio broadcasting. This arrangement combines tourism with the structure’s original function as a broadcasting facility.
The tower sphere weighs approximately 4,800 tonnes. Including the shaft, sphere and antenna system, the total mass of the TV Tower exceeds 31,000 tonnes.
Antenna mast and broadcasting technology
The antenna mast extends approximately 118 metres above the tower sphere. Together with the shaft and sphere, it gives the Berlin TV Tower a total height of 368.03 metres.
The tower was built as a transmission site for television, radio and other wireless communication services. It continues to perform this technical function today. The antenna system has been adapted several times to changing broadcasting standards; the modifications carried out in 1997 resulted in the tower’s present height.
The combination of a slender reinforced-concrete shaft, compact sphere and long antenna mast was therefore not determined solely by aesthetic considerations. Its form also reflects the structural, broadcasting and public-access requirements of the building.
Pavilion buildings and open spaces around the tower base
The location of the TV Tower formed part of the comprehensive redevelopment of East Berlin’s city centre. The tower was positioned within a planned “Central Axis” intended to extend from Karl-Marx-Allee across Alexanderplatz and the historic centre to the Brandenburg Gate.
The structure was designed to serve two purposes. It was to accommodate a powerful broadcasting facility while visibly representing the political and technological modernity of the GDR. Its height and reduced geometric form made it recognisable from large parts of the city.
According to the Berlin State Heritage Office, the TV Tower also documents a change in GDR urban planning. Earlier plans for monumental high-rise buildings gave way to a more technically oriented form of architecture. The TV Tower consequently became the dominant vertical feature of the redesigned city centre.
The TV Tower as a dominant feature of the cityscape
The architecture of the Berlin TV Tower also includes the low-rise buildings around its base. This base complex was constructed between 1969 and 1972 according to designs by Walter Herzog, Herbert Aust and Rolf Heider.
The pavilions have sloping roofs, some of which project freely beyond their supports. Their horizontal alignment forms a deliberate contrast with the vertical tower shaft. They also create a transition between the large technical structure and the surrounding pedestrian-level urban space.
The surrounding open spaces were designed between 1970 and 1973. Flower beds, water cascades, rose gardens, groups of trees and seating areas follow a geometric system aligned with the tower and pavilion buildings.
The TV Tower, its base complex and the surrounding open spaces therefore form a coherent architectural and urban ensemble.
A listed monument of GDR modernism
The Berlin TV Tower was recognised as a historic monument in the GDR in 1979. Today, it is listed in the Berlin heritage database as a protected ensemble together with its base complex and surrounding open spaces.
The protection therefore extends beyond the widely visible tower structure. It also includes the pavilion buildings and landscaped exterior areas. The ensemble documents the technological, architectural and urban-planning concepts of the GDR during the 1960s and early 1970s.
After German reunification, the TV Tower remained a central point of reference in Berlin’s skyline. Its former political function and its present use as a broadcasting facility and visitor attraction should be distinguished from one another, although both form part of the structure’s history.

Frequently asked questions about the architecture of the Berlin TV Tower
Here you will find concise answers to frequently asked questions about the architecture, construction and technical design of the Berlin TV Tower.
Who built the Berlin TV Tower?
The Berlin TV Tower was a state construction project of the GDR. The client was the GDR Ministry of Posts and Telecommunications, while construction was carried out by the Industrial Project Planning Berlin division of VEB BMK Kohle und Energie. The authorship of the design has never been conclusively established. Contemporary publications named Fritz Dieter and Günter Franke as the designers and Hermann Henselmann as artistic adviser. Gerhard Kosel later also claimed a significant role in the overall design.
How tall is the Berlin TV Tower?
The Berlin TV Tower is 368.03 metres tall, making it the tallest structure in Germany. When it was completed, its height was approximately 365 metres. Following modifications to the antenna system in 1997, the tower reached its present height of 368.03 metres.
When was the Berlin TV Tower built?
The Berlin TV Tower was built between 1965 and 1969. Work on the foundations began in August 1965. By June 1967, the reinforced-concrete shaft had reached its final height of 248.78 metres. The tower was put into operation in 1969 after the sphere and antenna structure had been installed and the interior completed.
How was the Berlin TV Tower built?
Construction began with the ring-shaped foundation, followed by the reinforced-concrete shaft, which was erected using a climbing formwork system. The steel framework of the tower sphere was initially assembled at ground level, dismantled into sections and then lifted by cranes to a height of around 200 metres. Once the sphere had been assembled, work continued on the antenna structure and the interior.
Why was the Berlin TV Tower built?
The tower was primarily constructed as a high-capacity broadcasting facility for television and radio. It was also part of the redevelopment of East Berlin’s city centre and was intended to form a prominent feature of the GDR capital’s skyline.
How was the sphere of the Berlin TV Tower installed?
The supporting steel framework of the tower sphere was first assembled at ground level as a trial construction. It was then dismantled into individual sections, lifted by cranes to the supporting platform at a height of around 200 metres and reassembled there.
How large is the sphere of the Berlin TV Tower?
The tower sphere has a diameter of 32 metres and contains seven floors. It houses the observation deck, the revolving restaurant and technical areas used for broadcasting and radio communications.
How deep are the foundations of the Berlin TV Tower?
The ring-shaped foundation has an outer diameter of around 42 metres. Depending on the section, it extends approximately 2.70 to 5.80 metres below ground level. Because the site has load-bearing layers of gravel and sand, the foundations could be built relatively shallowly in relation to the tower’s overall height.
