Šuplja Stena is a non-residential, recreational complex which in the period of two decades (1970–90) grew into one of the most popular children resorts, mostly for the group vacations organized by the Belgrade's elementary schools.
The complex covers and area of 12 hectares and includes 2 buildings, 14 bungalows, 3 open swimming pools, soccer, basketball and volleyball fields, etc.
Originally, due to the healing effect of the wind rose, Šuplja Stena was planned as an air spa for the rehabilitation of the children with respiratory problems.
It was operational until 1992 when Serbian government designated the place as a shelter for the refugees from Croatia and Bosnia and Herzegovina, after the outbreak of the Yugoslav wars.
