In the forecourt of the Lasipalatsi (“Glass Palace”) in the centre of Helsinki, a series of fluidly shaped domes swell from the ground to form an artificial landscape. This area is actually the roof of an underground museum in the Amos Rex cultural centre. As if not wishing to remain concealed, the museum ­complex bulges out of the asphalted courtyard and has transformed it into a popular meeting place. Finished with concrete tiles, the curved domes invite visitors to sit, play and skate on them.
