Docler supports the Szeged Open-Air Festival, a theatrical event with a history of over 80 years. The festival’s concept came from the poet Gyula Juhász in 1926 and was immediately backed up by several leaders in cultural and political life. Unfortunately, World War II meant the end of the series’ first act,
until its grand reopening on July 25, 1959. By the 25th anniversary of the Theater's re-installation, it was hailed as the country’s greatest outdoor theater. In the last years, they held 657 performances of 142 dramas and attracted three million viewers.
