James Logan may not be a household name, but he was a seminal figure in pre-Revolutionary America. He was secretary to William Penn and managed the daily affairs of the colony. Logan, who went on to hold almost every important public office in the colonies, designed the 1730 Georgian manor himself and named it for his father's birthplace in Scotland. He used it to entertain local luminaries and Native American tribal delegates. It was also where he kept one of the area's first libraries, at a time when books were looked upon with suspicion. George Washington was a guest of James's grandson on his way to the Battle of Brandywine, and British General Howe claimed it for his headquarters during the Battle of Germantown. The Stenton mansion is filled with family and period pieces; the site also includes a kitchen wing, barn, and Colonial-style garden. The guided 45-minute tour interprets the life of three generations of the Logan family and the life of the region from the 1720s through the American Revolution. This house has one of the best interiors of any of the Germantown homes. It's best to call ahead for a tour.
