Every year at the beginning of January, the Harbin Ice and Snow Festival in northern China stuns the world with its massive, complex ice buildings and ice replicas of prominent structures, but photos from the 2014 festival prove that this might be the best year yet. The 2014 gathering also had the added significance of being the 30th anniversary of the festival, so it's no surprise that the sculptors went all out. Some of the incredible ice replicas this year included the Empire State building, the Roman Colosseum, and most notably, the Hallgrimskirkja church in Iceland.

All of the structures are made with ice from the Songhua River, and extensive LED lights are used to colorfully light up each piece. The amount of work that was put into each replica is astonishing as the Hallgrimskirkja church alone is 46 meters tall and made with 12,000 meters of ice. Check out the photos from the magical festival!

Great aerial shot of all the ice replicas. So colorful, it looks like you are in a video game!

A replica of the Roman Colosseum-a much colder one.

This definitely looks like the rainbow level in Super Mario Kart.

Incredible replica of the Empire State Building!

The Hallgrimskirkja church has a 240 meter slide you can go down. Yes and yes!
