Danish design firm Monstrum (previously) continues to redefine the modern playscape, constructing numerous fantastical scenes for kids to climb on in locations around the world. Founded by Ole B. Nielsen and Christian Jensen, the award-winning firm has an extensive background in theatrical set design in theaters throughout Copenhagen that strongly influences their groundbreaking aesthetic. Each new playground becomes the backdrop for a dramatic scene, from towering robots to hoards of attacking insects. For their most recent creation in Moscow’s famous Gorky Park, Mostrum constructed a gargantuan octopus overtaking a huge oceanliner, complete with slides, cargo nets and climbing walls (shown above in subzero temperatures). See more recent work in their project portfolio.
