Treptower Park (pronounced [tʁɛptoːɐ], with a silent w) is a park along the river Spree in Alt-Treptow, in the district of Treptow-Köpenick, south of central Berlin. The park is a popular place for recreation of Berliners and a tourist attraction. It was also used for the concert given by the British Rock Band Barclay James Harvest on 14 July 1987, which was the first ever open-air concert by a Western Rock Band in the German Democratic Republic
Soviet war memorial 
Its prominent feature is the Soviet War Memorial (sometimes translated as the "Soviet Cenotaph"), built to the design of the Soviet architect Yakov Belopolsky to commemorate the 50,000 Soviet soldiers who fell in the Battle in Berlin in April–May 1945. It was opened four years after the war ended on May 8, 1949.
Within Treptower Park, there can be found an abandoned amusement park, known as 'Spree Park - Berlin'. The amusement park operated from October 1969 to 2001.
The owner of Spree Park, Norbert Witte went bankrupt and left Germany rather abruptly. He took several of the park's rides including the Jet Star and Fun Express with him to Peru where he was to open a small park called Lunapark at Jockey Plaza in Lima, Peru. Some of the rides were damaged in transit and then followed by legal discussions of who would pay for the damages.
