William B. Dunlap Mansion
William B. Dunlap Mansion, Greek Revival mansion in Bridgewater, Pennsylvania, United States.
The three-story brick mansion featured cedar wood interiors and stood prominently on a stone foundation overlooking the Beaver River.
Built in 1840 for coffee entrepreneur James Arbuckle, the mansion later belonged to Samuel R. Dunlap and his son William, a Pennsylvania State Senator.
The property contained underground tunnels discovered in the 1980s, suggesting its potential role in helping escaped slaves reach freedom in Canada.
The structure remained standing until January 16, 2017, when municipal authorities ordered its demolition due to severe structural deterioration.
The mansion grounds included what was considered the largest formal garden in western Pennsylvania during the nineteenth century.
