Until recently, this clock was the largest four-sided clock in the world. If you visit downtown Milwaukee or its near south side, it's hard not to see it, so in this sense it's really a "can't miss" when you come to town. Once a year, the public is invited to see the clock from the inside as part of the "Doors Open" event. As I write this, that opportunity is next weekend. I'm looking forward to checking out the tower.
