Extrapool is a venue and art space based in Nijmegen, The Netherlands, operating in three fields: sound, art and print.

Extrapool shows a diversity in sound art, performance art, short exhibitions and high quality printed matter. Concerts, workshops, screenings and book presentations are organized in Extrapool’s venue space on a regular base.

Extrapool is a great space for discovery. It shows work of upcoming artists and artists who work with multiple disciplines in art and music. At Extrapool, you never know what to expect; it’s all about the experiment. The events of Extrapool are characterized by their playful context in a convertible venue space. Informal and intimate on one hand, distinctive and artistic on the other.


Extrapool was founded in 1991 but Extrapool’s stencilprint workspace Knust has been around since the mid 80’s.

Knust started out as a workshop with analog machines by Gestetner and Roneo, which were easy to get your hands on back in the day, because the majority of offices and copy shops switched over to modern copy machines. Knust was interested in these analogue machines because of practical reasons (they could print reasonably fast, cheap and with several colors, and needed no cleaning) but mainly because of the beautiful way the greasy, colored ink would soak into the rough paper.

Before using these machines, Knust was already making a few offset and silkscreen books. After moving to Tweede Walstraat in 1991, Extrapool was born. From that moment on there would be enough space to create a venue/presentation room and even a sound studio in the basement. Nowadays Extrapool has a professional team of curators that work passionately on creating the most playful and surprising events.


On the top floor of Extrapool, there are two guest rooms with shared facilities such as a bathroom, small kitchen and a big balcony.

Artists in residence or artists who have performed in Extrapool can make use of the guest rooms. The beds are designed and made by Jan Vos and Ditte Havinga and inspired by old Dutch bedsteads. The guest rooms are also available for guests of other cultural initiatives. Send an e-mail to if you want to reserve or need more information.
