When a building is being constructed, ice is not a material that is typically employed. During the winter months, however, it works wonderfully well. This season, the Mall of America is hosting an impressive structure built from over one million icicles grown on site and fused together to create walls, towers, archways, seating, and more. The castle has been constructed over the past couple of weeks with the help of Brent Christensen, who has led similar ice-house projects around the U.S. The results stand over 40 feet tall at the peak, and span over one acre. As sections melt and refreeze with temperature fluctuations, the 50 connected towers will continue to morph and grow. Dress warm; there are many rooms to explore, from throne halls to mysterious caverns. The castle is even more striking at night, as LED multicolored lights illuminate the ice from within. Folks can also play in the children's snow park, or warm up outdoors with drinks and food. The Ice Castle: Mall of America is located in the north lot, next to IKEA.
