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.
The official record is held by a 96-foot tower built in Toronto last year. Link -via Gizmodo
