The main event in the festival is the outdoor theatre production of "Peer Gynt" at Gålå. The play is staged in "Peer Gynt"s birthplace, where Ibsen claims he found inspiration for the character "Peer Gynt", and is regarded by many as the most authentic version. The play is performed by professional actors from the national theater institutions, and nearly 80 local amateur actors. The music to the play is inspired by the original theatre music by Edvard Grieg – the "Peer Gynt suite". The play is one of the most popular theater productions in Norway, attracting more than 12,000 people every summer.
