Est. 1738 · Built 1738 by John Finney; home to future governor Nicholas Van Dyke · George Washington attended a wedding here in April 1784 · Subject of New Castle's first preservation effort (1931), founding the New Castle Historical Society · Listed on the National Register of Historic Places
The Amstel House stands at 2 East Fourth Street in New Castle, Delaware, a colonial-era town on the Delaware River. It was built in 1738 after John Finney purchased the property that year, and it stands among the better-preserved 18th-century mansions in the town's historic core.
The house passed through several prominent early-American households. Nicholas Van Dyke, who would become the seventh governor of Delaware, lived there, as did Kensey Johns, a member of the state's constitutional ratification committee, with his wife Ann. In April 1784 George Washington attended a wedding at the house — one of the events that anchors its place in New Castle's history.
The Amstel House became the focus of New Castle's first formal preservation effort. In 1931, concerned citizens raised funds to buy the house to protect the town's heritage; the group that formed around that campaign became the New Castle Historical Society. The society still owns the house and operates it as a museum, offering guided tours on weekends from April through December.
The building is listed on the National Register of Historic Places. Its long run of early residents and its place in the town's preservation story make it a regular stop on the society's history and ghost programming.

The Amstel House has carried a haunted reputation for close to a century, according to the New Castle Historical Society. Its executive director, Mike Connolly, describes the best-known figure as the "Lady in Blue," repeatedly seen in the upstairs bedroom windows and reported by people passing the house from the street. The identity of the figure is uncertain, and the society does not attach a documented name to her.
Staff also describe objects moving in ways they cannot explain. Connolly has recounted paintings and mirrors that hung on the walls being found on the floor afterward — not fallen and broken, but standing neatly against the wall, with the hanging hooks still intact and no one present at the time.
The New Castle Historical Society folds these accounts into its "Hauntings in History" tour, which pairs the town's ghost stories with its documented darker history of crime, punishment, and disease. The society is careful to frame the stories as accounts told to them by homeowners and business owners, some dating back to the 19th century, rather than as verified events. No independent confirmation of the Lady in Blue or the moved objects has been published.

Built between 1855 and 1859 for businessman William Butler Johnston at a cost of approximately $100,000, the Italian Renaissance Revival mansion at 934 Georgia Avenue has been called the 'Palace of the South' and is a National Historic Landmark. The house remained in Johnston hands through the Civil War, spared when Sherman's march to the sea bypassed Macon; it passed to the Johnstons' daughter Mary Ellen and her husband, Judge William Felton, in 1896. The Hay family acquired the house in 1926 and donated it to The Georgia Trust for Historic Preservation in 1977.
