Friendship Hill National Historic Site

Friendship Hill preserves the estate of Albert Gallatin, the longest-serving Treasury Secretary in U.S. history and architect of the Louisiana Purchase. This Pennsylvania site along the Monongahela River tells the story of early American democracy, westward expansion, and one man’s vision for a growing nation. It’s not a household name, but it shaped the country you know today. Wear it proud and spark conversations about the history hiding in plain sight.
