It was begun in 1803 for ironmaster John Dunlop.","why_significant":"The nomination argues the house is significant for its association with the charcoal iron industry, which it describes as a major factor in Centre County's early growth, and for its early 19th-century domestic architecture, influenced by the Federal style. It is presented as one of a locally prominent group of early ironmasters' mansions, and its interior woodwork is described as very high quality.","narrative":"Begun in 1803 and occupied by the John Dunlop family by 1808, this five-bay, two-and-one-half-story stone house overlooks the Logan Branch of Spring Creek in northern Spring Township. Its builder, John G. Lowrey, was Dunlop's cousin and plant manager, and the house was built opposite the Belle Fonte Forge. Its central hall contains a cherry circular handrail that spirals down to the first floor, and its entrance is framed by an elliptical fanlight and fluted oval columns. The house later served the Valentine family, who ran the iron works from 1822 to 1873, and it was used to entertain business guests during the negotiation for the Gratz Lands. Its stone office building, built around 1817, is the only surviving iron-works structure. The house is regarded as an important example of early domestic architecture in Centre County that reflects the wealth generated by the iron industry.","period_of_significance":"1803-1873","architect_builder":"John G.
