Before partnering with Caltech, AIM's founders planned a massive, highly specific headquarters in Morgan Hill, California. Popularly nicknamed the "Math Castle," the intended 167,000-square-foot facility was modeled directly after the Alhambra Palace in Granada, Spain. The layout relied heavily on mathematical tiling patterns, intricate geometric plasterwork, and courtyards. AIM founder John Fry (the billionaire co-founder of Fry's Electronics) personally drove the concept and design vision for this Andalusian-style fortress before the institute ultimately transitioned its operations to Southern California.
