Lego 21002 is a 77-piece set that allows you to build a detailed model of the Empire State Building, one of the most iconic skyscrapers in the world. The set is part of the LEGO Architecture series, which celebrates the world's most famous buildings and landmarks.

The Empire State Building model is made up of three sections: the base, the middle, and the top. The base is made up of a series of stacked boxes, which represent the building's foundation and lower floors. The middle section is made up of a series of towers, which represent the building's middle floors. The top section is made up of a spire, which represents the building's iconic antenna.
