Kiruna, Sweden, knows how to deal with snow: build a playground out of it. For the city's annual Snow Festival in January, PinPin Studio teamed up with ICEHOTEL and other local partners to create this winter wonderland featuring a maze, ice slides, seating, and a "snow lantern" that glows at night. The entire playground took less than a week to build.
The walls of the snow maze are three meters tall, with some sections built out of translucent ice to "enhance directional confusion." The playground is flanked by two massive hills, where you can scope out your escape route ahead of time.
