As downtown Danbury expanded in the late nineteenth century, commercial buildings were constructed on side streets. One is example is Library Place, formerly a cow path, which was opened after the construction of the Old Danbury Library in 1878. Here, Alexander Wildman built a post office, followed by other commercial buildings, including the Seifert Armory in 1891. Located at 5-15 Library Place, the large armory and commercial building, designed by architect Joel Foster, has storefronts on the ground floor, while the three upper floors contained apartments and the armory hall, itself later converted to apartments. In the 1920s, the Danbury Times began printing in the building and a plate-glass window was installed to show the press at work. The building has lost its original tower that projected above the main entrance. The farthest store on the left now has a Carrara glass (a type of pigmented structural glass) storefront.
Connected to the Seifert Armory and extending up the steep slope of Library Place at Nos. 17-21 are a row of three attached apartments, built in 1892 and also designed by Joel Foster.
