The Mulberry Plantation, in 1679, granted to Sir Peter Colleton and was acquired by Thomas Broughton in 1712. Thomas Broughton was the Commons House of Assembly Speaker for about 4 years starting from 1726. He then became a Governor in 1735.

The mansion, built in Jacobean baroque style, was also a refugee site for several people during the Yemassee War.

The mansion's present state is brought about by Broughton who allegedly modeled it in 1714 after England's Seaton Hall.

It is believed that it is called the Mulberry Plantation because it was named after the Mulberry tree marking the boundary of Sir Peter Colleton's 12,000 acres of land. Its other names include Polly, Salt Point, Mulberry Castle, and South Mulberry.

At present time, it is still privately owned. However, there are 8 other North Carolina Landmarks within its 5 mile radius.
