The foundation of an eighteenth-century building involved in a famous robbery by Bucks County’s Doan Gang during the American Revolution has been discovered by archaeologists in Newtown, PA.
The Bucks County Treasury was robbed by the infamous "Doan Gang," a network of Loyalists in Bucks County who supported Great Britain during the American Revolutionary War. The Gang robbed tax collectors, militia members, and other citizens who supported the Revolutionary cause. 244 years ago to the day, on October 22, 1781, the Gang made off with twelve hundred Spanish silver dollars, four hundred French crowns, and a large amount of cash – tax money that was meant to fund the Revolution.
Phase I archaeological testing was conducted on the site of the former Bucks County Treasury in Newtown in May 2025, part of a project sponsored by the Mercer Museum & Fonthill Castle, operated by the Bucks County Historical Society (BCHS), as part of research for the museum’s ongoing major exhibition The Doan Gang: Outlaws of the Revolution.
Working with Matt Bielecki of Stony Hill Archaeological Research, BCHS staff and members of the community excavated four test pits on the site of the former Treasury. Many members of the public witnessed the excavations and even had a chance to learn archaeological methods from Bielecki and his staff. The archaeologists found parts of the original foundation as well as many different kinds of artifacts, including an English pistol gunflint.
BCHS Senior Director of Collections, Exhibitions, & Historical Properties Cory Amsler notes, "We are very grateful to Matt Bielecki for coordinating this preliminary excavation, as well as to the property owners and members of the Newtown Historic Association who helped make the excavation possible. We anticipate that the artifacts recovered in the dig will eventually enter the collections of the Historical Society's Mercer Museum - some to be placed on view in conjunction with our ongoing Doan Gang exhibition."
The original Treasury building, which was once part of a complex that also included a prison and 1 courthouse, was demolished in 1873. For decades it was unclear whether anything remained of the original structure. The recent archaeological testing put that mystery to rest.
“It was so exciting when we actually hit rock and lime mortar in the test pits, exactly where historic maps of the old building told us we should," said BCHS Exhibit Specialist Clint Flack, who participated in the excavations and co-curated the Doan Gang exhibition at the Mercer Museum. “To think there’s still something left of the building that the Doan Gang encountered on that night in 1781 really makes the history of that time period come alive.”
The artifacts found during the excavations will be analyzed in Bielecki’s laboratory, and a full report on the project will be completed. BCHS and Bielecki hope to conduct further Phase III testing on the site in Spring 2026, where more of the original foundation and other artifacts from the Doan Gang’s time may be discovered.
