Originally know as Allen-Bradley, parts of the building are approximately 100 years old. The clock tower was completed in October of 1962. The majority of the clock components were designed and built by Allen-Bradley employees. Until recently, it was the largest 4 sided clock in the world. It is now the largest 4 sided clock in the Western Hemisphere. Currently undergoing extensive renovation, each side of the clock is lit by fluorescent tubes requiring nearly 35 kilowatts of power.
