The Brandenburg Gate, in the heart of Berlin, has often been the scene of German history over the centuries. For nearly 40 years, it symbolized the division of the two German states, until it became, with reunification in 1990, a symbol of freedom and of a reunified Germany.On the occasion of the 30th anniversary of German reunification, the Brandenburg Gate is offered as a 150-piece 3D puzzle, which reproduces not only the gate itself but also the two adjacent buildings.
