What started with peasants using ice lanterns to hunt and fish at night has expanded into one of the largest ice festivals in the world, drawing in hundreds of thousands of visitors every year. The festival in Harbin kicks off in northeastern China every Jan. 5, when the temperature averages -36 F. More than 15,000 artists work to craft the incredible ice sculptures, which are lit up every night to create a garishly beautiful icescape featuring tributes to the Forbidden City and Great Wall among other landmarks.
