It's an anarchist bookfair, but clearly non-sectarian, as it also invites a lot of non-anarchist groups or speakers. From 11h to 14h, there will be workshops in English. The entrance is for free.
The location? Not far from a train station in Ghent, north of Belgium.
Stalls are mostly from Belgium or The Netherlands, but there are also some initiatives from other countries :
