Doors Open Milwaukee is an annual celebration of Milwaukee’s architecture, history and neighborhoods. The event opens 160+ locations throughout the metro area to tour for free! Ever wondered how Carmex, the beloved lip balm, is made? Now’s your chance to get a behind-the-scenes look! While the building itself may seem like a standard warehouse, the real treat is inside—the world’s largest theater pipe organ, featuring 6,500 pipes, a grand piano, percussion instruments, and more. Families can stop by to listen to live music on the incredible organ, with a mix of popular and classical tunes played throughout the day. It’s a one-of-a-kind auditory experience that both kids and adults will enjoy. Why Kids Will Love It: Listening to the booming sound of the massive organ is sure to amaze music-loving kids (and maybe inspire future musicians!).
