Alea 101, Mixed-use building in Alexanderplatz, Berlin, Germany

Alea 101 is a freestanding five-story cube about 30 meters tall, designed by Berlin office Sauerbruch Hutton and completed in 2014. Its lower three floors hold shops and restaurants, while the upper two contain offices and 14 apartments. It stands at the corner of Gontardstrasse and Rathausstrasse, south of Alexanderplatz station and near the Television Tower.

The site housed the first German C&A store from 1911 until 1949, when it was taken during the East German period. The current building was later built on this same spot, continuing its role as a commercial center.

The name Alea comes from Latin for "cube", referring to the building's shape, and 101 marks the years since C&A opened its first German branch on this site in 1911. The ground floor houses a Vapiano restaurant alongside retail space. The site previously held the Haus Bukarest national restaurant, which opened in the ground floor on 18 December 1956 and had to leave at the end of 1967.

The building sits at the corner of Gontard and Rathausstrasse between Alexanderplatz station and the Television Tower, making it easy to reach by public transport. Its central location helps with navigation and provides quick access to nearby points of interest.

The name Alea 101 combines the Latin word alea, meaning cube, with the year construction began: 2012, exactly 101 years after the first German C&A branch opened on this site in 1911. The building was designed by the Berlin office Sauerbruch Hutton, chosen by a jury on 26 November 2009.
