Landing Place of William Penn
Visiting New Castle in May of 2026 was so much more than I expected. It was my first time exploring this historic town, so everything was new to me. As I drove into town, my first impression was that I had arrived in Williamsburg, Virginia. It didn’t take long, however, to realize that unlike Williamsburg, which was carefully reconstructed, New Castle is the real thing. Here is a remarkably preserved colonial town where the streets, homes, churches, and public buildings have stood for centuries. Exploring its buildings, monuments, and waterfront was an exciting step back into early American history.

One of the most significant discoveries was this historic marker commemorating the landing of William Penn. Near this spot, on October 27, 1682, Penn first stepped onto American soil before continuing north to establish Philadelphia.
What I found especially interesting was learning that Penn did not come to America intending to found Delaware. His dream was Pennsylvania, the colony granted to him by King Charles II in payment of a debt owed to Penn’s father. However, Pennsylvania had no direct access to the Atlantic Ocean without control of the Delaware River. Before Penn could begin his “Holy Experiment” of religious freedom and representative government in Pennsylvania, he first had to take possession of the Lower Counties on the Delaware, lands that had been transferred to him by the Duke of York. In many ways, New Castle became the gateway to Pennsylvania. Although Penn is remembered as the founder of Pennsylvania, his first official act in America took place here in Delaware.
The marker describes the ancient English legal ceremony known as “livery of seisin.” Upon arriving at the fort, Penn was formally presented with its key, along with a piece of turf bearing a twig and a vessel containing water and soil from the Delaware River. These symbolic gifts represented the legal transfer of the Duke of York’s lands into Penn’s possession. Though the ceremony may seem unusual today, it marked the official beginning of Penn’s authority over the Lower Counties and paved the way for the establishment of Pennsylvania and the future State of Delaware.

Delaware’s Independence Hall
One of the things I learned while exploring New Castle was that Delaware’s path to independence did not begin in Dover, but here at the Old Court House. This building is often referred to as Delaware’s Independence Hall and why it occupies such an important place in the history of the First State. Constructed in […]
Courtroom of the New Castle Court House
Standing inside the courtroom, I was reminded that this building witnessed far more than the birth of a state. Decades after Delaware declared its independence within these walls, the courthouse became the setting for another defining chapter in American history: the struggle over slavery and the Underground Railroad. In 1848, this courtroom was the site […]
Frenchtown Railroad
One of the most fascinating stories I discovered in New Castle was that this small colonial town became the eastern terminus of one of America’s earliest railroads. Completed in 1832, the New Castle and Frenchtown Railroad stretched just sixteen miles across the Delmarva Peninsula, linking the Delaware River with the Chesapeake Bay. Although the railroad […]
