Visitors can explore this empty castle and its beautiful surroundings, once part of a vast 9,000-acre estate that includes the nearby Brookgreen Gardens, the first public sculpture garden in the U.S.
2. Gassaway Mansion
In Greenville, South Carolina, the Gassaway Mansion is a striking example of 1920s architecture. Built between 1919 and 1924 by Walter and Minnie Gassaway, the Mansion combines Neo-Gothic and Neo-Classical styles. Minnie, who learned architecture through correspondence, influenced its design.
The estate includes a tower, a stone carriage house, and a stone power house, adding to the charm of its grounds. Listed on the National Register of Historic Places in 1982, the mansion now hosts weddings and special events, offering a glimpse into South Carolina’s architectural history.

Doomsday Castle still stands as a fascinating example of modern medieval construction, blending past and future in a compelling way.
4. Castle Pinckney

Built to protect Charleston from naval attacks, Castle Pinckney was the first military installation surrendered to Southern forces after South Carolina’s secession.

Listed on the National Register of Historic Places in 1970, Castle Pinckney offers a fascinating glimpse into the Palmetto State’s past.
