Bellevue Hall began as Woolton Hall, a Gothic Revival residence built in 1855 for wool merchant Hanson Robinson and his wife Anne Poultney. The original house leaned heavily into the castellated, towered fashion popular in mid-19th-century Atlantic seaboard estates. In 1893 the property was acquired by William du Pont, scion of the Delaware industrial dynasty, and on his death in 1928 it passed to his son William du Pont Jr.
William du Pont Jr. was an avid horseman and an admirer of Montpelier, his estate in Orange County, Virginia. In a series of remodels through the 1930s, he stripped Woolton Hall of its Gothic detailing and reclad it as a Neo-Classical pavilion modeled closely on Montpelier's facade, complete with a pediment portico and symmetrical wings. The result is the building visitors see today: a 19th-century shell carrying a 20th-century costume.
The State of Delaware purchased 270 acres of the estate from the du Pont family in 1976 and incorporated the mansion and grounds into Bellevue State Park. The mansion is operated as a wedding and event venue and is occasionally opened for guided tours and seasonal programs run by the Delaware Division of Parks and Recreation. Notable occupants of the upper floors during the du Pont era include Margaret Osborne, William Jr.'s second wife, and Margaret Varner Bloss, both championship sportswomen who lived at the property in the mid-20th century.
The second and third floors, where staff have historically reported the most unusual activity, are generally not part of the public mansion tour and are accessed only during occasional paranormal programs.

Reports from Bellevue Hall tend to cluster on the second and third floors, which are not part of the standard tour. Staff and contracted event workers have described chairs in the dining rooms found rearranged in geometric patterns when the building was empty, lights flickering despite a comprehensive rewiring, and the sounds of laughter and occasional screaming when the mansion was locked overnight.
Diamond State Ghost Investigators, the regional paranormal group most often associated with Bellevue Hall, have published session evidence including EVP recordings that they interpret as voices of women associated with the du Pont occupation of the property - in particular Margaret Osborne and Margaret Varner Bloss, who lived at the mansion during the mid-20th century.
Delaware State Parks runs occasional 'Paranormal 101' programs at Bellevue Hall. These evening events are the rare opportunity for the public to access the upper floors of the mansion, and they are typically ticketed and capped at small group sizes. Outside of those programs, the upper floors remain administratively closed.
A docent-led tour of the main floor of the 1855 mansion, remodeled in the 1930s by William du Pont Jr. into a near-replica of his Montpelier home. The upper floors, where staff have reported the most unexplained activity, are typically closed to the public.
Delaware State Parks periodically partners with paranormal researchers for ticketed evening investigations of the mansion, including access to the second and third floors otherwise closed to the public.
Walk the formal lawns, reflecting pool, and tennis courts that surround the mansion. The 328-acre park preserves much of William du Pont Jr.'s estate landscape.

Colossal Cave Mountain Park preserves a dry limestone cave 15 miles southeast of Tucson that became notorious in the 1880s as a hideout for train robbers. The loot they stashed inside was never found. Frank Schmidt, one of the cave's early developers, spent much of his life documenting and preserving the caverns before his death.

Historic Sotterley is the only tidewater plantation in Maryland open to the public, with a 1703 Manor House and an 1830s slave cabin standing on 94 acres above the Patuxent River. It is a National Historic Landmark and a UNESCO Site of Memory tied to the Trans-Atlantic Slave Trade.

Carnton, built in 1826 in Franklin, Tennessee, served as the largest temporary Confederate field hospital after the November 30, 1864, Battle of Franklin. Approximately 300 wounded soldiers were treated inside the house in a single night, and four Confederate generals' bodies were laid out on the back porch the following morning. Carrie and John McGavock later donated land for the McGavock Confederate Cemetery on the property — the largest privately owned military cemetery in the United States.
