I went to Viktoriapark in Kreuzberg with my friends Elliott and Ben. We had radlers in the Biergarten and then walked up the hill to the Prussian National Monument for the Liberation Wars, which actually predates Germany as a nation (1821). It is a beautiful Neoclassical spire commemorating the German Campaign of 1813 during the Napoleonic Wars. From the top of Kreuzberg you can see the entire city. It was a fun afternoon.
