I did a quick search for interesting things in the area while I was in the airport waiting to take off for business travel. I was going to be in the Milwaukee area and wanted to see "Dr. Evermor's Sculpture Park" and this came up as a nearby attraction.
I am really glad I added this little museum to my itinerary. It's on a former military gunpowder and bomb factory property, which I believe most of has been given back to indigenous people.
The museum itself is in (I think) a visitor's center or welcome building. Most of the rest of the original plant is gone.
In a fairly small space, they pack a ton of interesting information, artifacts, news clippings, videos, and material from the original plant. The docent also knew a lot about the operation and history.
There's lots of interesting information here about women factory workers, how ammunition was made, explosions at the plant, and interesting tidbits like how smoking was forbidden, even though it was very popular (much more so than now) and how they tried to ensure nobody had lighters or matches or cigarettes. read more
