Carré Alte Post - Acquired by Dolphin Capital GMBH for 7.5 Million Euros Built between 1925 and 1929, "Post Office Lichtenberg I" on Dottistrausse is a striking and impressive 4-story building in Berlin. With a deep history spanning over seven decades, the post office was a hub of communication throughout some of the city's most troublesome years. Built in an era when highly decorative and ornate facades were being forgotten, it was purposely in an economical and practical style. The office was built by the Berlin Oberpostdirektion and remained a major focal point for postal communications until 1945. After World War II, the Soviet Army took over the building and set up a long-distance telephone operator for the telephone service in the Soviet Union. The Stasi, one of the most effective and repressive intelligence and secret police agencies known to ever have existed, also used the building as a "listening centre" and also set up a "safe house" in the building. A number of years later, another telephone centre was established in the west wing of the building which was responsible for connecting the telephone network in East Berlin. After the reunification of East and West Germany, the Telecommunications Office was also reunified and operated until 1995. The building lay idle until 2013 when Dolphin bought the building. It is currently working on constructing 48 luxurious apartments within the walls of the historic building. It's also constructing four residential buildings with 90 stylish individual apartments on the additional courtyard, with a large common green area.
