The open air theatre in Indelukket was established in 1945. The theater was built as an employment project, so all earthwork was done with wheelbarrows to provide work for as many as possible.
Benches were set up enough to seat up to 6,000 spectators.
It turned out  that the theater was too big. So in 1984 it was reduced to 2,000 seats.
Today the Open Air Theatre provides the setting for the open air rock festival Hede Rytmer as well as for the annual the Country Festival. Furthermore, it is also frequently used for outdoor concerts.
