The Etmaal takes place across the following locations in the city centre (all within walking distance of each other): the Harmonie Complex, Turftorenstraat, the Academy Building, and the House of Connections. During the Etmaal, volunteers will be available to point you in the direction of your workshop location. Note that NS organizes buses from Groningen Europapark to Groningen CS, more information about work on the railway system here.
