The Hagley Museum is fascinating. It is a gunpowder factory that helped make the DuPont fortune and is quite a large campus. You can walk or take the shuttle and the tours are very informative. Situated along the Brandywine river, there are many mills and building to explore. Learn how gunpowder was made and many other interesting things. Our favorites were the tour of the gunpowder mills, run by gravity powered water turbines (it ends with a BANG) and the machine shop (so jealous). The museum is near the DuPont Estate and both can be seen in a day if you are ready to walk. I Highly recommend visiting, especially if you like engineering, machines, etc.
