Est. 1817 · National Historic Landmark (1986) · Philip Hooker neoclassical architecture · Clarke family colonial New York history · Glimmerglass State Park historic feature
George Clarke (1768–1835) was a wealthy Albany landowner and the great-grandson of a colonial acting governor of New York. He purchased lakeside property on Otsego Lake's northeastern shore in 1817 and commissioned Albany architect Philip Hooker to design a country villa. The project unfolded in three distinct phases over seventeen years.
The first structure, known as the Stone House, followed Palladian principles with a two-story hip-roofed core flanked by one-story wings. A second phase added plain fieldstone servant quarters. The third and most ambitious phase produced the Great House, a neoclassical block notable for one of the earliest uses of Doric columns in New York State, with grand entertaining rooms measuring 34 by 26 feet each.
George Clarke died in 1835 before the full project was finished. His descendants occupied the mansion and managed the surrounding agricultural estate for decades. The property eventually passed out of family hands and fell into serious disrepair before a preservation campaign in the late twentieth century stabilized and restored the building.
The National Park Service designated Hyde Hall a National Historic Landmark on June 24, 1986, citing its architectural significance and the completeness of its documentary record. The mansion is set within Glimmerglass State Park on the lake's eastern shore. A historic covered bridge built simultaneously with the mansion in the early nineteenth century still stands on the property.
Hyde Hall Inc. operates the mansion as a museum, offering house tours late May through Halloween and October ghost tours. The Syfy channel's Ghost Hunters filmed an investigation at the property in Season 9, Episode 16, titled 'Hyde and Seek.'

George Clarke died in 1835, a year before Hyde Hall's final construction phase was complete, which local tradition holds as an explanation for why he is said to remain. The reports at Hyde Hall are among the longer-standing in the Otsego County region — apparitions and unexplained sounds have been described at the mansion for the better part of two centuries, though documentation of specific incidents before the modern era is thin.
The Haunted History Trail of New York State lists Hyde Hall as an active paranormal site and notes that Clarke is 'far from the only presence said to remain' at the mansion. The nature of the additional presences is not further specified in primary documentation. The range of reported phenomena — full-body apparitions, phantom footsteps, distant music, whispered voices, and phantom knocking — is consistent across multiple investigation accounts.
Syfy's Ghost Hunters sent a team to Hyde Hall for Season 9, Episode 16, broadcast under the title 'Hyde and Seek,' providing a televised investigation record. The episode is listed on IMDB.
Hyde Hall's October ghost tours, branded 'Hyde & Shriek,' have run for multiple seasons and consistently draw visitors to the isolated lakeside property. The venue advises that these tours are not appropriate for young children.

Charles City, VA
Benjamin Harrison IV built the current mansion at Berkeley Plantation in 1726, making it one of the oldest three-story brick houses in Virginia. The plantation became the birthplace of President William Henry Harrison in 1773 and the ancestral seat of a family that produced a signer of the Declaration of Independence and two U.S. Presidents. During the Civil War, General McClellan used the mansion as his headquarters and the cellar held Confederate prisoners.
Macon, GA
Built between 1855 and 1859 for businessman William Butler Johnston at a cost of approximately $100,000, the Italian Renaissance Revival mansion at 934 Georgia Avenue has been called the 'Palace of the South' and is a National Historic Landmark. The house remained in Johnston hands through the Civil War, spared when Sherman's march to the sea bypassed Macon; it passed to the Johnstons' daughter Mary Ellen and her husband, Judge William Felton, in 1896. The Hay family acquired the house in 1926 and donated it to The Georgia Trust for Historic Preservation in 1977.
