Excelsiorhaus
From Wikipedia, the free encyclopedia

The Excelsiorhaus is a residential and commercial high-rise building in the Kreuzberg district of Berlin, located at Stresemannstraße 68–78. It was designed from 1965 as an apartment building modeled on developments in New York City by the Berlin architectural firm Sobotka and Müller,[1] and constructed between 1966 and 1968 for Excelsior Tankstellen GmbH & Co. KG.[2] The company belonged to investor Artur Pfaff.[3][4]
After initial financing difficulties, construction costs amounted to approximately 50 million Deutsche Mark (equivalent to roughly several hundred million euros in today's purchasing power).[5] The building is 59.7 m tall, has 18 storeys, and offers 33,203 m2 of usable space, including 506 apartments and 39 commercial units.[6] Since summer 2011, it has been owned by the holding company of investor Nicolas Berggruen.[2]
The name refers to the former Hotel Excelsior, which stood on the site before World War II and was considered one of the largest hotels in continental Europe.
The 16th and 17th floors of the Excelsiorhaus contain premises for a gastronomic establishment. They are connected internally by a spiral staircase and can be accessed via a glass external elevator running along the northern façade, which travels non-stop between the ground floor and the 16th floor. At the time of the building's opening, this panoramic elevator was the first of its kind in West Berlin and was regarded as an attraction.[5]
In the early years, the Canadian restaurant Saskatchewan occupied the space. Its highly visible illuminated sign initially gave the building the nickname “Saskatchewan high-rise”.[7]
Later, the nightclub Turn Tower used the premises, becoming particularly popular within the West Berlin art scene in the 1980s. After several years of vacancy, the Solar Bar opened there in December 2005.[7]
On the ground floor, there was a nine-pin bowling alley until the early 2010s, as well as, for a short time, the Café Europa, where cars could also be purchased.[5] In 2014, a branch of the supermarket chain Lidl opened on the ground floor. Since 2019, the basement has housed the Basement Boulderstudio.
A fallout shelter for around 3,100 people was opened beneath the Excelsiorhaus in 1976.[8] It included medical rooms, a soup kitchen, 40 toilets and washbasins, and its own well at a depth of 60 m. The emergency power generator ran on diesel fuel and consumed 50 liters per hour. The tanks held up to 27,000 liters, allowing occupants to remain sheltered for up to 14 days.[9]
