The Georgetown Castle

The Georgetown Castle—Gessner Mansion—is not merely a Victorian relic of Georgetown’s past, steeped in more than a century of ghost stories and rumor. It is more than a residence. It is a watchtower.

Built in 1902 by Peter Gessner—a gambler and blackjack dealer at the Central Tavern in Seattle’s Pioneer Square—the house was intended for his young wife, Lizzie. Within a year, he was found dead under gruesome and contested circumstances. Some claimed suicide by drinking carbolic acid; others whispered of murder—an act of betrayal involving either Lizzie or her alleged lover, the manager of Gessner’s chicken farm in Sunnydale (present-day Burien) pouring it into his mouth while asleep. Whatever the truth, his presence is said to linger, Gessner is the first of many ghosts said to haunt the Castle, making it legendary—the quintessential haunted house.

It was constructed on the 1851 land claim of Luther Collins, and in 1902 the Castle was a beautiful new imprint on the emerging grid of the Georgetown neighborhood—some draw simulations to the modern McMansion. Perched on a bend of the once-wild, meandering Duwamish River, it stands as an early expression of domestic grandeur and over the years it has quietly borne witness to more than a century of transformation, both visible and unseen.

Before 1851, this meandering Duwamish River was home to the Duwamish people—the Dxʷdəwʔabš—whose relationship to the land and water extended back through time immemorial. The river’s seasonal rhythms—its flooding, shifting channels, and abundant salmon runs sustained a complex cultural and ecological systems. What followed was not only settlement, but the deliberate re-engineering of an entire landscape. By 1917, the river had been straightened, dredged, and confined in one of the region’s most sweeping acts of environmental transformation. Wetlands were filled, tideflats hardened, and the organic complexity of the watershed gave way to rail corridors, sawmills, shipyards, and eventually heavy industry.

From the Castle’s turret, this transformation unfolded in full view. Steam whistles replaced birdsong; the scent of cedar and saltwater yielded to coal smoke and petroleum.

With this transformation came another layer of human experience: the stories we tell each other and ourselves to make sense of rupture. Ghost stories arise in places where the past has been unsettled and where landscapes change faster than memory can reconcile. In Georgetown and along the Duwamish, these stories are more than tale of apparitions in hallways, alleyways, or figures in windows; they are expressions of deeper dislocation. They speak to what has been buried or erased, and to the uneasy coexistence of past and present. The haunting here is not only spectral—it is ecological, cultural, and historical.

In this way, the Castle becomes more than an architectural gem. It stands between worlds: river and industry, memory and modernity, presence and absence. Its turret reinforces this role—a watchtower bearing witness to both change and consequence.

Today, its windows look out over one of the most contaminated industrial waterways in the United States, shaped by more than a century of fossil fuel dependence, maritime logistics, and industrial production. The designation of the lower Duwamish as a Superfund site makes this legacy explicit, linking a local landscape to global systems of exchange.

And yet, to stand in the turret now is also to see possibility.

Fun Facts:The Castle's internal skeleton tells the true story of the valley. In the crawl spaces of the third floor, you can find 2”x4”s marked with the stamp of the Newell’s Sawmill in South Park. The grain is dense, old-growth timber harvested from a world that no longer exists. These beams are the literal 'bones' of the ancestral landscape, repurposed to support a gambler’s Victorian dream. They are a silent, structural memory of the massive trees that once shaded the Dxʷdəwʔabš villages, now hidden behind lathe and plaster.
