It sits on an estate of about eight acres with gardens and a gate house.","why_significant":"The nomination presents the estate as a reminder of an era of great economic disparity and conspicuous architectural display. The mansion is described as a significant work of Renaissance Revival architecture and a unique residence in the Cleveland area because of its carved granite construction and ornament. The house, garden and grounds are noted as one of few well-preserved estates of the era.","narrative":"Built between 1910 and 1912 on Ridge Road in Wickliffe, Ohio, this granite mansion was the home of Harry Coulby, an English immigrant who rose to a leading position in Great Lakes iron and shipping. It cost over $1,000,000 and was designed by Cleveland-area architect Frederic W. Striebinger. The H-shaped Renaissance Revival building is about 145 feet long and 85 feet wide, with a balustraded parapet, Ionic pilasters and columns, arched openings, and carved oval medallions and foliage swags, all in granite. Inside are eight Italian marble mantelpieces, paneling from Bohemia and Tiffany colored glass. The original garden layout, a curved retaining wall, a gate house and a broad lawn toward the road survive within an eight-acre boundary. The building now serves as Wickliffe City Hall, with modest changes such as an enclosed porch, a fire escape and jail cells. It was listed as a well-preserved example of an early twentieth-century estate and of Renaissance Revival design.","period_of_significance":"1910-1912","architect_builder":"Frederic W.
