The property includes a main house, stone tower, grill house, arbor, gazebo and other outbuildings.","why_significant":"The nomination argues the property is significant in architecture as an intact interpretation of a European manor house with a French flavor, and in recreation and tourism as a summer estate from the Thousand Islands' wealthy-resident era. It is also tied to Carl J. Zimmerman, the New York City industrialist who founded Carbola Chemical Company, a major regional employer for over 50 years.","narrative":"Fairview Manor, first called Longue Vue Manor, is a French Eclectic stone residence completed around 1937 on a knoll above the St. Lawrence River in Clayton, New York. The 2-1/2-story house is built of local river rock with 3-foot-thick walls, a slate roof, turrets, dormers and a large river-facing terrace. The estate also has a 50-foot stone tower that once held a working windmill, a grill house, a stone-pillared arbor, a gazebo, and stone gateposts. Carl J. Zimmerman, a New York City industrialist, built it as a summer retreat. He founded Carbola Chemical Company, a talc-mining business that employed many people in the North Country for over 50 years. The property is recognized for its intact architecture, which may reflect Zimmerman's travels, and for its place among the summer estates that shaped the Thousand Islands tourism economy. Walter Anstey is named as builder.","period_of_significance":"c.1937","architect_builder":"Anstey, Walter (Builder)","architectural_style":"French Eclectic","criteria":["B","C"],"status_note":"The main house is described as very intact, with a 2001 kitchen extension.
