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! Step inside the beautifully redeveloped Pabst Boiler House (originally built in 1890!) where Milwaukee’s newest classical music station, Wisconsin Public Radio’s 90.7FM, calls home. The building itself is a mix of preserved cream city brick, timber joists, and sustainable design features—including a 4,500-square-foot green roof. From here, afternoon drive host Jason Heilman broadcasts live classical music across Wisconsin, while the local news team delivers statewide coverage. Visitor Experience Families will love this peek behind the microphone! Guests can step inside the broadcast studios, talk with engineers and news staff, and see firsthand how live radio is made. With access to the studios and chances to meet the people behind the voices, it’s an interactive experience for kids and adults alike. Why Kids Will Love It: They’ll get to explore a real radio studio, chat with radio hosts, and see how sound travels from the mic to the airwaves. Please note: Dates and times are subject to change, and occasionally events may be cancelled. Please check the event website to confirm the latest details.
