It is also tied to Adam Mappa, a Holland Land Company agent, and to the settlement of New York State. The house became the area's social center and Mappa helped found the liberal religious society that became Barneveld's Unitarian Church.","narrative":"Mappa Hall is a limestone house in the village of Barneveld, Oneida County, built between 1801 and 1809 for Adam Gerard Mappa, a Dutch printer turned land agent for the Holland Land Company. The two-and-one-half-story main block is five bays wide and has a projecting central pavilion with a pediment and a portico of four Corinthian columns. Inside, a wide center hall holds a curved stairway with a mahogany and ivory handrail, and the formal rooms have carved woodwork and fireplaces with marble or slate facings. The house sits within a three-acre park beside the Unitarian Church. Its significance rests on its Federal style design, its well-preserved character, and its link to Mappa and the settlement of New York State. It was planned to match Lorenzo in Cazenovia, though Mappa exceeded the company's building allowance and could not finish it as he wished. The house became a social center and has remained a private residence.","period_of_significance":"1800-1899","architect_builder":"Adam J.
