This fountain and sculpture had been in it's designated location only for 15 years, between 1903 and 1918. The statue depicting the mythological figure of benevolent "Father Rhine".
That location was at Strasbourg in front of the theater. What some patrons in Strasbourg disliked was the view of bare buttocks when they left their theater or when they were just enjoying a walk in the park.
Though the area, Alsace, had always been bilingual, 1870 after the war between Germany and France, Alsace was claimed and annexed by Germany. Only after WWI in 1918 it had to be returned to France. Since the fountain and statue were considered "too German", it was dismantled.
The artist, Adolf von Hildebrand, worked in Munich, so the city of Munich bought the pieces in 1929 and rebuilt them in 1932 on an island in the river "Isar" ...
Now the statue has a nice blue/green patina, but you can picture from the colorized vintage postcards that the bronze was golden-brown in the beginning.
