The Isaac Meason House, also known as Mount Braddock, is a historic house located in Dunbar Township, Fayette County, Pennsylvania. Completed in 1802, it is one of only two surviving Palladian style stone mansions from the period in the United States. Isaac Meason, for whom it was built, was an American Revolutionary War hero and early political power broker in the area, becoming the richest person in Fayette County due to his interest in iron furnaces and possession of enslaved people. The house was designated a National Historic Landmark in 1990 for its architecture.
