Neptunbrunnen

The Neptune Fountain in Berlin was built in 1891 and was designed by Reinhold Begas. The Roman god Neptune is in the center. The four women around him represent the four main rivers of Prussia at the time the fountain was constructed: the Elbe , Rhine , Vistula , and Oder . The Vistula is now entirely in Poland, while the Oder forms the border between Germany and Poland.
The fountain was removed from its original location at the Schlossplatz in 1951, when the former Berliner Stadtschloss there was demolished. Eventually, after being restored, the fountain was moved in 1969 to its present location between the St Mary's Church and the Rotes Rathaus.
