It was built between 1918 and 1923 by Dr. Frederic R. Calkins and includes a main camp building, outbuildings and a suspension bridge.","why_significant":"The nomination presents Knollwood as a small-scale example of a private Adirondack camp that follows the principles of camp construction, with separate function-specific buildings built from local materials in a natural setting. It remains virtually intact from its construction and retains an outstanding degree of integrity. It is also tied to its designer-builder, Dr. Calkins, a Watertown surgeon, and includes a 103-foot arched suspension bridge he designed.","narrative":"Knollwood is a summer camp on a knoll above the Oswegatchie River in the Town of Fine, near Star Lake, St. Lawrence County. Dr. Frederic R. Calkins, a Watertown surgeon, bought the land in 1915 and designed and built the camp between 1918 and 1923. The main building is a two-story, cross-gabled structure of whole spruce logs with cement chinking, with screened porches, exposed rafters and wide overhangs, reflecting Adirondack rustic style with Stick and Bungalow touches. A generator/workshop and a 103-foot arched suspension bridge, both built by Calkins, also contribute to the property. A storage shed, outhouse and water tower are later or rebuilt and do not contribute. The interior keeps its original plan, finishes, built-in cabinets and much of its furniture. Knollwood was far smaller than the Adirondack Great Camps, yet it followed the same ideas of a planned site, separate buildings for particular functions and local materials. Its integrity of setting, design and craftsmanship is described as outstanding.","period_of_significance":null,"architect_builder":"Dr. Frederic R.
