The park continued its evolution during the cold war . An open air theater was constructed at the southern end of the park in 1950 , and after recent renovation remains open today . In preparation for the 3rd World Festival of Youth an Students two pools were constructed during the period from 1949 – 1951 . The complex included a 5-meter deep pool for diving , and an 8-lane , 50-meter long swimming pool , along with stands for up to 8000 spectators ( Karl-Friedrich-Friesen Stadium ) . Around 1963 , the swimming pool received a collapsible mobile roof that allowed for winter use , although the roof was incorrectly constructed as it was too low . School swimming events , competitions training took place at the stadium , and it also served for other mass events such as Hauff and Henkler 's appearance during the 10th World Festival of Youth and Students in 1973 . Due to the conditions of the pool basins and degradation of the bleachers , the facility was demolished in 1999 . Only the four lantern pillars of the western gate remain , which were made in the workshop of Karl Souradny in 1951 . In GDR times a youth recreation camp existed in the park , the Indianerdorf ( Indian village )
