Its walls are ashlar limestone quarried at Little Falls and laid by masonry contractor Martin Easterbrook. The five-bay front faces Main Street under a gabled roof with a narrow cornice and an oval window in the gable. The main entrance has a Federal doorway with a broad elliptical fanlight, a stone arch and engaged columns beside the sidelights, reached by a double set of steps with an ornate cast-iron railing. A south wing, with a flat roof and Italianate bracketed eaves, repeats the quoins and window pattern of the main block. The building was recognized as an important example of the Federal style common in the Mohawk Valley and as a well-preserved part of the civic complex at Main and Court Streets. It was documented by the Historic American Buildings Survey in 1937.","period_of_significance":"1835","architect_builder":"Martin Easterbrook, masonry contractor","architectural_style":"Federal","criteria":[],"status_note":"Listed as in good condition, altered, on its original site, and owned by Herkimer County.
