Harriton House, originally known as Bryn Mawr, is an historic house which is located on the Philadelphia Main Line, and was most famously the residence of Founding Father Charles Thomson, the secretary of the Continental Congress.
It was added to the National Register of Historic Places in 1973.[1]
Originally built in 1704 by Rowland Ellis, a Welsh Quaker, it was called Bryn Mawr, meaning high hill. The modern town of Bryn Mawr is named after the house, and the National Register of Historic Places has it listed under the original name.
It was originally designed as a T-shaped, two-story fieldstone dwelling with a gable roof. The original front section is approximately thirty-seven feet wide and twenty-two feet deep and the rear extension is approximately eighteen feet wide and twenty-three feet deep. A one-story brick kitchen was added to the end of the rear extension. The house was renovated in 1911 and major additions were made in 1926.[3][4]
It was added to the National Register of Historic Places in 1973.[1]
