Bring out the long underwear.

For Minnesotans still yearning for more snow and cold, the new icicle wonderland at the Mall of America might be your fix. It opens Monday.

The massive ice castle will glimmer and shimmer with thousands of LED lights at the shopping mecca, featuring several throne rooms with large ice chairs, archways and an abundance of ice towers.

Ice Castle LLC, a Colorado-based company, is calling the spectacle the largest castle it has built. All it took was 4 million gallons of water and tons of ice to fuse the 50 large towers together. There also is a play area where kids can build a snowman or play on a snow-covered hill.

Maybe you can leave the long underwear at home -- the ice castle has outdoor fire pits to keep you cozy.
