Discover the Allen-Bradley Clock Tower Tour in Wisconsin

See Milwaukee’s most iconic landmark up close with a rare behind-the-scenes visit to the Allen-Bradley Clock Tower, also known as the “Polish Moon.” Once the largest four-faced clock in the world, this massive timepiece is part of the Rockwell Automation headquarters on Milwaukee’s south side.
Why it’s special:
The clock tower is a historic symbol of Milwaukee’s industrial legacy, and access inside the structure is rarely granted—making any arranged tour a truly unique experience.

History/Story of the Allen-Bradley Clock Tower

Built in 1962 by the Allen-Bradley Company (now Rockwell Automation), the 280-foot tower features four clock faces each measuring 40 feet across—bigger than London’s Big Ben. For decades it held the title of the world’s largest four-faced clock. The clock became a beacon for workers, travelers, and nearby neighborhoods, earning its affectionate nickname: “The Polish Moon.”
