Tour George Mason’s Gunston Hall

Gunston Hall, completed in 1759, was the plantation home of George Mason, one of the Founding Fathers of the United States.

Mason wrote the Virginia Constitution and the Virginia Declaration of Rights which is the basis of the U.S. Bill of Rights. If you didn’t know that, it’s okay. He’s often considered our “forgotten” founding father.

When you visit Gunston Hall, the tour starts in the museum where exhibits share what life was like when George Mason lived here. Many exhibits challenge you to think about issues of civil rights, equality and representation. These issues, which still cause our nation to stumble from time to time, were major issues even back in the 1700s.

After the museum, walk over to Gunston Hall and gardens to learn more about the family’s life here.

The home itself is an outstanding example of Georgian architecture and is highly regarded for its elegant interiors. The elaborate interior carvings, designed by indentured servant William Buckland and carved by William Bernard Sears, provide an impressive backdrop for guided tours of the 18th-century plantation household.

Museum staff have developed interactive elements to make it easier to think about life in the late 1700s as it was. One example is a table with everyday items to consider whether they are locally made or imported.

Another example shows playing cards as they looked in the late 1700s. On the back of the cards, read some of the issues that were debated over card games, much like happens today.

Behind the house, the family’s gardens are recently rehabbed to be more consistent with how they would have looked when the Mason family lived here. The staff has also taken the time to research and grow crops that enslaved families would have grown so that visitors learn the full story of everyone who lived at Gunston Hall.

Interpretive gardens at Gunston Hall

I tour historic homes all over the country, and some stand out — Biltmore in North Carolina, and Monticello in Virginia to name two. Gunston Hall is a smaller property, but it is amazing. The museum team’s creativity has made history easier to understand than many places I visit.

It’s part history education, for sure. But, it’s also high on my list of kid-friendly things to do in Fairfax, VA because the presentation is interactive, not dry.

Gunston Hall is located at 10709 Gunston Rd, Mason Neck. Gunston Hall is open daily from 9:30 a.m. to 5:00 p.m., and is closed Thanksgiving Day, Christmas Day, and the first two weeks of January.

I found myself grinning on the Imagination Express ride, despite being really bad at hitting the targets. If you’re familiar with Walt Disney World, it’s not unlike Buzz Lightyear’s Space Ranger Spin.
