Buildings made of ice. We're not talking about that novelty bar you visited on a trip to Vegas. We're talking incredible, impressive, complete structures built in the grand tradition of Ice Palaces all over the world.

Bundle up. This might get chilly.

The very first ice hotel was erected in 1990 in Jukkasjärvi, Sweden. Made out of 10,000 tons of ice "harvested" from the Torne River, Icehotel is rebuilt every year.

St. Paul started holding its annual Winter Carnival after a snooty New York reporter wrote that Minnesota was "unfit for human habitation" in the winter. Its yearly centerpiece? This impressive ice palace.

Eagle River, Wisconsin is another small midwestern town that builds an ice palace every year. It started back in the 20s because apparently there wasn't much else to do. Seriously, that's the explanation on the town's website.

Of course we can't talk about ice buildings without going to the Great White North. The ice palace at Quebec's annual winter carnival is so amazing, it almost doesn't even look like it was made out of ice.

While we're in Québec, we must mention the beautiful Hôtel de Glace, the only ice hotel in North America. Made of 15,000 tons of snow and 500 tons of ice, it has 36 rooms and hosts around 140,000 visitors every year.

It also has a chapel.

The Lainio Snow Village in Finland opens every year in December and stays open at least through April. It even has an ice disco.

The LumiLinna Snowcastle in Finland is so crazy and cartoonish it looks like it was inspired by a fairytale monstrosity.
