Coghlan Castle

Coghlan Castle

Saint John, North Dakota

If Coghlan Castle seems out of place, it is because there are over 60 known examples of this unique building style in Manitoba, Canada, but only one in North Dakota. Maurice Coghlan hired a Canadian architect, Thomas Boyner, to design this house and hired a Canadian mason to build it. The house, built between 1906 and 1909, is constructed from local granite, limestone, and sandstone. Years of neglect damaged the structure, but a non-profit group raised money to restore and protect this authentic resource. It was listed in the National Register of Historic Places in 2008.
