The Stiegel-Coleman House, also known as Elizabeth Farms, is a historic mansion house at 2121 Furnace Hills Pike (Pennsylvania Route 501), just north of Brickerville, Pennsylvania. Built in 1757 and substantially enlarged in 1780, it was the home of two of colonial Pennsylvania's early iron and glass makers, William Stiegel and Robert Coleman. The furnace they operated, whose archaeological remains were rediscovered in 2004, was one of the most successful in the Thirteen Colonies, and provided war materials for Continental Army. Their house was declared a National Historic Landmark in 1966. It has remained in the hands of Coleman descendants, mostly as a private residence.
