The Fifth Regiment Armory is a historic National Guardarmory built in Baltimore, Maryland, United States in 1901. The Armory is a fortress-type structure situated in midtown Baltimore. It consists of a full basement, a first floor containing a 200 foot by 300 foot drill hall, a mezzanine or "balcony" level, and a newer second level (reconstructed in 1933 after a fire) housing the trussed steel drill hall roof. The façade features buttresses, parapets, casement windows, and a crenellated roofline, giving the appearance of a medieval fortification.[2] It was the site of the 1912 Democratic National Convention.
The Maryland Museum of Military History, housed at the Armory, collects artifacts and runs programming related to Maryland's militias, dating back to Colonial times, and present-day branches of the military.[5]
