The LEGO® Millyard is the largest permanent LEGO® installation at minifigure scale in the world, as recognized by Guinness World Records® here.
The installation at SEE represents Manchester’s Amoskeag Millyard as it might have looked circa 1900. The Amoskeag Manufacturing Company was commonly recognized as the largest textile manufacturer in the world by 1915. The Amoskeag mill complex spanned over a mile on the east side of the Merrimack River and half a mile on the west side. This model represents a portion of the east side, along with part of downtown Manchester, the city that the Amoskeag company helped to build.
This project marked the first time the LEGO® Company worked on a creative display of this scale with outside partners. These partners include: the SEE Science Center, FIRST (For Inspiration and Recognition of Science and Technology), CLD Consulting Engineers, and NELUG (the New England LEGO® Users Group). The City of Manchester also sponsored this project. The Manchester Historic Association provided research materials, and awarded SEE with an Historic Preservation Award for the project in 2006.
