Berlin from the victory columnThe Victory Column is a monument created to commemorate the Prussian victory in the Danish-Prussian War. It's possible to visit this monument and climb the the stairs to get to the top of the column where you can find very interesting views of the capital city.
The 3rd of October is a national holiday when the German celebrate their "Unity Day" (Tag der Deutschen Einheit). This is normally a really good day to walk along the "Straße des 17. Juni", since it''s open only to pedestrian traffic. I did that walk last year, visited the column and shot the picture you can observe above.
