It's the tallest Lego tower ever, soaring to the heavens at more than 104 feet and setting a geek world record last week.
The Lego World Tower brought joy to the hearts of Koreans last week when it went up in Seoul's Olympic Stadium.
At 104 feet and 7 inches, it edged out a similar tower erected in France last year at 103 feet. It took some 4,000 Korean kids five days and half a million bricks to put it together.
Danish Crown Prince Frederik laid the final bricks to crown the tower, an assembly resembling Seoul's famed Namdaemun gate.
The event also marked the 80th anniversary of the founding of the Lego group. The plastic bricks themselves turned 50 in 2008.
The first Lego tower was built in London in 1988 and was just under 50 feet tall, according to The Daily Mail. Dozens of other plastic towers have been built since.
