A festival for improvised theatre in Bielefeld in the Tor6 Theaterhaus - with international artists, workshops and a diverse show programme at the highest level - that is the Impro Fest Bielefeld.

For 4 days, Bielefeld becomes the center of spontaneous theater - every evening there are unique theater evenings that inspire and touch.

The improvisational theatre scene meets to work and celebrate together - over 100 improvisation enthusiasts travel from all over Germany and Europe.

In November 2025, the Impro Fest Bielefeld will be entering its 5th round - created in 2020, in the middle of the pandemic as IFO - i.e. as Impro Fest Online - we have long since become an offline event and inspire the Bielefeld audience year after year.
