Partnership Mansion

The Partnership Mansion (commonly referred to as Hall Manor) was a mansion located on the grounds of Six Flags America in Largo, Maryland. The original structure was built by the Hall family in the 1700s, and was added on to by subsequent owners notably the Berry family in the 1840s.

History
Partnership was a large, two-story, brick plantation house built in the eighteenth century and the 1840s. The house had a Georgian plan, a flared gable roof and walls of Flemish bond; the main and rear facades had glazed header bricks. This building incorporated parts of an early eighteenth-century Hall family home; on the grounds is a single Hall family tombstone dating from the early eighteenth century.

The house had undergone several rebuildings, including a major renovation during the residence of the Berry family in the mid-nineteenth century. It was presumed that remnants of a brick kitchen building known to have existed at the end of the eighteenth century may have exist under the nineteenth century frame kitchen. Partnership exhibited features of both the Federal and Greek Revival styles, and was an important county landmark.

Plans were made in the late 1990s to restore the mansion, and to use it as offices for Six Flags America, but it was deemed too costly. While other plans were being developed to save the property, in 2005 an exterior wall collapsed destroying any salvage plans. The rest of the home collapsed in the January 2011 blizzard.

The Haunting of Hall Manor
The Haunting of Hall Manor is a Fright Fest experience at Six Flags America first introduced in the 1990s, it is themed around the derelict mansion, and named after Ellinor Hall, the 5-year-old daughter of the Hall family that is buried on the premises.

Following the COVID-19 pandemic, the attraction re-opened in 2021 as The Haunting of Hall Manor: The Return of Eleanor Hall.
