The local summer festival Mladifest was launched in 1995 and is currently organised by the Student Club Sežana, with its main partners being theKosovel Culture House Sežana and MC Podlaga. It is mostly held at different outside venues around the town of Sežana and has an extensive and very diverse programme that addresses the whole of the local community, though mostly it is aimed at the younger generations.
Mladifest consist of several different programme segments, with the most dense and varied one possibly being the children’s programme which involves workshops, puppet shows, music performances, and the like. There are also sports events and competitions, round tables, lectures, gaming events, movie screenings (including the Animateka after Animateka programme of Animateka International Animated Film Festival), theatre plays and music concerts (presenting both mainstream and more alternative bands and artists like Elvis Jackson, Moveknowledgement, Blaž, Koala Voice, and Vlasta Popić). Artistic installations and fashion exhibitions also sometimes take place, with the latter consisting of works by young and emerging fashion designers.
