Top 15 Historical Sites in Delaware!

History: It runs all through the state of Delaware like the Christina River, picking up momentum as the years go on, passing down new stories to the coming generation. Since Delaware was technically the first state to establish European settlements, much of that history is well preserved and celebrated. Pre-European Delaware was also a sight to behold and we’ll be covering that as well with our picks for the top 15 historical sites in the state.

1. The Old State House, Dover, DE

The building that was once the capital of the entire state is none other than the Old State House, a stately looking period building that’s almost as well preserved as the history inside of it is. The Old State House Museum goes to great lengths to take its visitors way back in time, revisiting the deep and meaningful history of the Native Americans who once resided on this very land. If retellings of the Underground Railroad and the shoreline settlements of the Native Americans intrigues you, this is a great stop to add to your itinerary.

2. Auburn Heights Preserve

Classic antique automobiles shine beside a 6,000-square-foot, slate gray mansion that peaks out in the shimmering night, putting on a display that could rival The Great Gatsby. Lovers of architecture and automobiles alike will have an unexpectedly pleasant time at this off the beaten track attraction nestled deep within the newest state park in Delaware. Highlights of the museum include a ride along the old trolley line, a look at the mills of the legendary Marshall family, 390 acres of rolling hills, the largest operating collection of Stanley steam cars in the world and the antique furnishings of a once affluent family on display. Please review their website for scheduling and touring. Hours of operation vary.

3. The Nanticoke Indian Museum, Millsboro, DE

4. First State National Monument, New Castle, DE

An understated landmark if ever there was one, this site is the original rocks that Finnish and Swedish settlers were believed to have set foot on when entering the Americas. Just a stone’s throw from here is the Kalmar Nyckel, a replica ship inspired by this moment in time.

5. Winterthur Museum, Garden, and Library, Wilmington, DE

A colossal collection of history awaits in a stately mansion full of opulence and pristine. Winterthur’s Museum, Garden, and Library both holds history and is history.

From books, to manuscripts to decorative arts and horticultural wonders, history never looked so good on Delaware. Admission packages start at a humble $10 per person and rates escalate depending upon length of tour, membership status, etc. Winterthur is often seasonally decorated and occasionally experiences season based closings so keep an eye on their website for hours of operation as they change throughout the year.

6. Wilmington and Western Railroad, Wilmington, DE

The expansive Red Clay Valley opens up before you as you experience history hands on by taking a train through time. The back roads of Delaware’s history are intricate, jumbled and picturesque, especially from the seat of a historic locomotive. The railroad itself was once part of an 1867 passenger line. Seasonal tours are often made available during select times of the year while varying weekend tours cover a diverse array of historical topics. 

7. University of Delaware Mineralogical Museum - Penny Hall, Newark, DE

The story of civilization can be told from many different vantage points, but this museum brings a whole new meaning to the phrase hidden gem.

8. Parson Thorne Mansion, Milford, DE

The history of Milford is housed between the red bricks of this classic vintage mansion. Home of former Governor William Burton, the eerie house on Silver Hill is rumored to be so deeply rooted in Delaware’s past that it connects with paranormal activity.

9. Nemours Mansion and Gardens, Wilmington, DE

This classic attraction was first presented to Delaware via the famous DuPont family. With over 77 era-accurate rooms showcasing history and refinement, this richly appointed museum is a local and national treasure. Touring the grounds will give you a glimpse into the mid-1800s and the French influence that was often present in colonial America. The acre-long pool complete with a cascading fountain is certainly a draw but for history buffs it’s the architecture, the sculptures, the figurines and the trim, that make it stand out.

10. Middle Point - Mason Dixon Marker, Delmar, DE

Just along route 54, in the Delmar section of Delaware, is a somewhat overlooked roadside attraction with an odd history attached. It’s the site where Mason and Dixon began dividing the United States. Here is where North went South all the way back in 1764.
