The Lego brick tower stands nearly 100ft tall and is shaped to resemble a Viking longboat mast

Made of almost half a million bricks, the structure has been built to celebrate Lego's 50th birthday

Youngsters helped build 20cm sections that were raised into place by crane

The park’s special events manager, Penny Jenkins, said: “We are thrilled to bring the World Record to Legoland Windsor after four days of hard work, not to mention nearly 500,000 bricks, and it now stands at nearly 100ft.

“It has been a great way to celebrate the 50th anniversary of the Lego bricks.” The record attempt is awaiting official verification by Guinness World Records.
