Unter den Linden is a tree-lined east–west avenue that extends from the Brandenburg Gate to the site of the former Berliner Stadtschloss, and was Berlin's premier promenade in the nineteenth century. Many classical buildings line the street and part of Humboldt University is located there. Friedrichstraße was Berlin's legendary street during the "Roaring Twenties" and today, it combines twentieth-century traditions with the modern architecture of contemporary Berlin. Places of significance in the area include the Admiralspalast, the Friedrichstadt Palast, and the Theater am Schiffbauerdamm, home to the Berliner Ensemble. Potsdamer Platz is a quarter that was built in its entirety after the Berlin Wall was deconstructed in 1995. To the west of Potsdamer Platz is the Kulturforum, which houses the Gemäldegalerie, and is flanked by the Neue Nationalgalerie and the Berliner Philharmonie. The Memorial to the Murdered Jews of Europe, a Holocaust memorial, is situated to the north. The Hackescher Markt was constructed as a joint endeavour between the Berlin City Commandant, Graf von Hacke, and Friedrich II. In 1840 it was officially renamed as Hackescher Markt. The area around Hackescher Markt is home to fashionable culture, with countless clothing outlets, the offices of international fashion labels, clubs, bars, and galleries. The Hackesche Höfe is also a part of the area and is a conglomeration of buildings that were reconstructed around 1996; the buildings now surround several courtyards. Oranienburger Straße and the nearby New Synagogue were the center of Jewish culture before 1933. Although the New Synagogue is still an anchor for Jewish history and culture, Oranienburger straße and surrounding areas have become increasingly known for pubs, shopping, theaters, art galleries, and nightlife. The Straße des 17. Juni, connecting the Brandenburg Gate and Ernst-Reuter-Platz, serves as a central East-West axis. Situated in the western part of the city, its name commemorates the uprisings in East Berlin of June 17, 1953. Approximately half-way from the Brandenburg Gate is the Großer Stern, a circular traffic island on which the Siegessäule ("Victory Column") is situated. This monument, built to commemorate Prussia's victories, was relocated from its previous position in front of the Reichstag in 1938 by the Nazis.
