About the inspiration:
The Cathedral of Learning, a Pittsburgh landmark listed in the National Register of Historic Places, is the centerpiece of the University of Pittsburgh's main campus in the Oakland neighborhood of Pittsburgh, Pennsylvania, United States. Standing at 535 feet (>163 m), the 42-story Late Gothic Revival Cathedral is the tallest educational building in the Western hemisphere and the second tallest university building (fourth tallest educationally-purposed building) in the world. It is also the second tallest gothic-styled building in the world. The Cathedral of Learning was commissioned in 1921. The Cathedral is a steel frame structure overlaid with Indiana limestone and contains more than 2,000 rooms and windows. [source: http://en.wikipedia.org/wiki/Cathedral_of_learning]
About the build:
Originally created for a LEGO builders competition at a local toy store (S.W. Randall in Squirrel Hill), the building was not built to true scale due to the 10" height limit of the contest. After winning the adult category, the model was redone to the intended height, which is just under 1 foot.
After much attention online and at LEGO Kidsfest 2012, I digitally recreated it in LEGO Digital Designer in order to preserve the build as well as produce (~500 pages of) instructions for others to build.
