This silhouette is the Quadriga sculpture above the Brandenburg Gate in Berlin, Germany, which I visited some years back. The Brandenburg Gate is a popular tourist attraction, and it was really crowded when I was there. The Quadriga is a sculpture of a two wheeled chariot pulled by four horses, and it symbolises peace entering the city while the gate itself symbolises unity (source).
Other than the Brandenburg Gate, there's also plenty of other interesting landmarks depicting the history of how it was divided into two, and later re-unified. I'll be back some day for a visit!
