Fodor's Expert Review Rose Hill Manor Park/The Children's and Farm Museum

The home of Maryland's first governor, Thomas Johnson, the mansion has been reinvented as a children's museum. Costumed interpreters lead kids through the house and grounds, where they can dress up in period clothing, weave on a loom, and play with reproductions of toys from the 1700s and 1800s. Visitors can also explore a collection of carriages, a log cabin and blacksmith shop, herb gardens, and a smokehouse.
