English: Oswego City Hall, 13 West Oneida Street at West First Street, as seen from the plaza in front of the Conway Municipal Center, Oswego, New York, February 2021. Built in 1870-71, the building was designed by prominent Syracuse-based architect Horatio Nelson White and sports a handsome French Second Empire design of the type that was popular in the era for use in grand municipal buildings. The gray Onondaga limestone façade is replete with Classical details: windows come topped variously in segmental and round arches, the latter crowned with unusual Florentine-arch window heads; the entrance is framed by two pairs of stylized engaged Corinthian columns; the requisite mansard roof is faced in slate, colorfully striped, and crowned with handsome widow's walks over the projecting portions flanking the entrance. The tower contains a set of bells that "for many years... signaled unusual events", according to the historic site inventory filed with the St. Lawrence-Eastern Ontario Commission. Oswego City Hall was listed on the National Register of Historic Places in 1973.
