These bronze sculptures (entitled Drei Mädchen und ein Knabe - three girls and a boy), by Wilfried Fitzenreiter, used to sit around the fountain of the Palast Hotel, which stood on the corner of Karl Liebknecht Straße.
The hotel was demolished in 2001 and the sculptures were moved to their current location on the eastern bank of the river Spree in 2007.
The building behind them is the Berliner Dom (officially called the Oberpfarr- und Domkirche zu Berlin, the Berlin supreme parish and cathedral church), by Julius Raschdorff, completed in 1905, though slightly altered in its post war rebuilding. Perhaps I'll say a bit more about it later - its history is yet another interesting part of the story of this area of Berlin.
While I stood there looking at the sculptures, a seemingly constant procession of tourists came past to have their pictures taken with them. I have to admit they have something very lifelike about them. You could easily imagine that they were just sat relaxing by a pool somewhere...perhaps even enjoying an ice cream...
