The Forum is Groningen's most striking modern building — an angular ten-storey cube of stacked galleries, clad in grey stone, anchoring the east side of the Grote Markt. Inside is a public library, the new Storyworld comic museum, a cinema with five screens, an extension of the Groninger Museum, and a series of cafes that wind up to the roof.
It is free to enter and wander. The rooftop terrace, reachable by escalators and lifts, has the best free city view in Groningen — there's no need to climb the Martini Tower if you don't fancy the steps.
