Stonum, also called Stoneham or the George Read House, was the home of George Read, a signer of the Declaration of Independence. His advocacy enabled Delaware to become the first state ratifying the declaration. The house is located in New Castle, Delaware and was declared a National Historic Landmark in 1973.
The house was built beginning circa 1730 with what is now the kitchen. The front portion of the house was added before 1769. The house is 2-1/2 stories with an L-shaped plan. A further addition was made in 1850, while a concrete block porch was added in the 1920s. Interiors are well-preserved. The house once enjoyed an expansive view of the Delaware River, now obscured by industrial development.
