Constructed from 1802 to 1819, Teackle Mansion is now a museum that offers exhibits and historic furnishings from the time period to preserve the history of life for of Littleton Dennis Teackle and Elizabeth Upshur Teackle. The Princess Anne mansion is the largest and oldest brick building in the community.
Littleton Teackle was a leading businessman whose company supplied the lumber which was used for the construction of the United States Capital. The family's fortunes reversed a decade after the mansion was complete and the family was eventually forced to sell the grand estate. After many years of being empty or serving as home to apartments, the building was restored and is now operated by the Somerset County Historical Society.
