Beneath the Courthouse
Sometimes the most interesting history is literally beneath our feet. Inside the New Castle Court House, this small glass opening in the floor reveals part of the foundation of the first courthouse built on this site in 1689.
The remains were discovered during renovations to the courthouse in the 1950s. Rather than covering them again, a portion was left visible, allowing visitors to look down into the earliest layer of the building’s history.
That first courthouse stood here from 1689 until 1729, when its history came to a dramatic end. At the time, a prisoner named William Kelsey was being held in the courthouse jail awaiting execution after being convicted of breaking and entering.
Kelsey managed to escape from his cell. Hoping to create enough confusion to allow him to get out of town, he used his candle to set fire to the courthouse. His plan was that the burning building would distract the townspeople while he made his escape. It didn’t work. Kelsey was recaptured, and the courthouse was destroyed by the fire. He was subsequently tried for arson and hanged in March 1730.
A new courthouse was constructed on the site beginning in 1730, creating the building that became the center of some of Delaware’s most important political and legal events. In 1776, representatives meeting here voted to separate from Pennsylvania and Great Britain, an important step in the creation of Delaware as an independent state.

What makes this little window on the floor so interesting is that it takes us back even further. Beneath the eighteenth-century courthouse where Delaware history was made are the remains of its 1689 predecessor—and behind those stones is the remarkable story of a condemned prisoner, an escape, a deliberately set fire, and the destruction of New Castle’s first courthouse. Without this small opening in the floor, we could walk directly over that story and never know it was there.

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, […]
Court House Museum
One of the highlights of our visit to New Castle was the historic Court House, one of the oldest surviving courthouses in the United States. Standing before this building, it is easy to appreciate that it was much more than a courthouse. For nearly a century, it served as the center of government for Delaware, […]
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 […]
