White Plains Armory

Why it's listed
Built in 1909 at 35 South Broadway, the White Plains Armory is a castellated brick building designed by New York State Architect Franklin B. Ware for local National Guard units. A two-story front section with a four-story crenellated tower and octagonal turrets faces the street, while a 100-by-150-foot drill hall extends behind. Red sandstone trim and foundations give it a warmer look than most military buildings. Ware followed published guidelines for armory design, calling for towers, narrow windows and a fortress-like character. The site is historically important too: the county's first courthouse stood here, and the Declaration of Independence was read from its steps in 1776. A granite monument beside the building commemorates that event. Company L trained here before World War I service, and the building later served civil defense and Air National Guard needs until 1976. It remains largely as designed and is one of three armories in Westchester County.
Significance in brief: The nomination calls it an outstanding example of the castellated style and one of only three armories in Westchester County. Ware closely followed contemporary armory design guidelines, and the building is one of only four downtown White Plains structures predating the city's 1916 incorporation. The site also held the county's first courthouse, where the Declaration of Independence was first read in New York State, and the armory became a center of community and wartime activity.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
