Grenland Friteater is one of the oldest independent theatres in Norway, based in the small industrial town Porsgrunn.
Every year in June, Grenland Friteater organises the Porsgrunn International Theatre Festival.
Trond Hannemyr, Lars Vik and Tor Arne Ursin are still a part of Grenland Friteater.
In the early 80s, the theatre was reinforced by actors Geddy Aniksdal and Anne Erichsen, and producer Hans Petter Eliassen.
The festival contains New Circus, comedies and outdoor plays in world class, and it has become part of the city's identity.
