Here is what Wikipedia tells us about the park:
"In the 1950s, rose plantations were planted in the Rose Valley.
At the end of the 1960s, the park saw some improvement. New lanes were laid, concrete dams were built, and lakes were purified of silt.
Now the central section of the park is decorated with a cascade of lakes covering nine hectares. About 50 varieties of trees and bushes grow there. There is a stage with a capacity of 1000 spectators, a small amusement park with a Ferris wheel, and several restaurants..."
