Walnut Hall, also known as the Willie P. Mangum House, was a plantation in Durham County, North Carolina, near Bahama.

Walnut Hall was a 600-acre plantation that produced tobacco, corn, and wheat through the forced labour of enslaved people.

Walnut Hall was built by the politician Willie Person Mangum, who served as President pro tempore of the U.S.

[3] The house, originally styled after the nearby Fairntosh Plantation, was constructed between 1842 and 1845 in northern Durham, near Red Mountain, in present-day Bahama.

[3] Through forced labor of enslaved people, Walnut Hall produced wheat, corn, and tobacco as cash crops.

[3] After Mangum inherited debts from his father, his father-in-law, William Cain of Pleasant Grove Plantation,[7][8] saved him from financial ruin.

[11] After the death of her husband, Charity Cain Mangum and her daughters continued to resided at the plantation, where they managed the farm while selling off portions of the land to their neighbor, Zachariah Hampton.

[3] The property remained in the Hampton family until 1977 when it was acquired by the North Carolina State University's School of Forestry and was added to the adjacent G.W.
