The tallest structure built with interlocking plastic bricks was 30.52 m (100 ft, 1 in) high and was constructed by the Stichting Limmen Ludiek (Netherlands) foundation on in Limmen, Netherlands, on 6 June 2010. The tapered tower structure took more than three days to build and required the assistance of more than 1,800 volunteer workers.
The first section was placed by Kim Rosner Pedersen, first secretary at the Danish embassy in The Netherlands. Two engineers from LEGO - Per Knudsen and Karsten Niebuhr - also travelled from Denmark to assist in overseeing the attempt.
