The armory is constructed in the Art Deco architectural style and was added to the National Register of Historic Places in 1991.
Renovations are planned to update the building in 2010 and to the 15-acre tract of land between Penn and Grove streets.
The land has been owned by the National Guard since it was given to the state in the 1920s by the mother of Garrett Cochran, who died in France while serving as a lieutenant with the National Guard during World War I.
