Mill Run

About this city

Also known as: The Home of Fallingwater

Mill Run is a small, historically profound rural mountain hamlet nestled within Stewart Township in Fayette County, located deep in the rugged, heavily forested topography of the Laurel Highlands in southwestern Pennsylvania. The community achieved monumental international architecture fame as the immediate home of Fallingwater, the extraordinary 1935 residential masterpiece designed by legendary architect Frank Lloyd Wright for the Kaufmann family, which is now a UNESCO World Heritage site. Positioned along the dramatic, rushing waters of Bear Run, the area is defined by its roaring sandstone gorges, dense rhododendron thickets, and deep mountain isolation. Today, Mill Run serves as a premier global pilgrimage destination for architectural scholars, nature photographers, and outdoor enthusiasts exploring the wild rivers of the region.
