Take a tour of the stunning Chinese art festival that stretches more than 112 football fields of pure ice

If Elsa from "Frozen" ever needs help building her ice castles, she might want to check out the talent behind the Harbin Ice Festival.

The annual event, held in the city of Harbin in northeastern China's Heilongjiang province, boasts some seriously impressive ice and snow art built to monumental scale.

It took 10,000 workers and three months of design work to construct the massive exhibition, which covers more than 112 football fields. Now in its 32nd year, the festival is a tourist favorite despite the sub-zero temperatures.

Elsa, eat your heart out.
