The Altoona Armory, or as it is commonly known by resident; the Frankstown Armory, is one of the historic places listed in the National Register of Historic Places in Blair County PA. The Altoona Armory is a National Guard facility located in Logan Township, Blair County, Pennsylvania.
The main armory building was built in 1938, and is an "I"-plan building in the Moderne style. The front section housed administrative functions and the rear was the former two-story stable area for the cavalry unit. Between these sections is the riding hall, which has a round arched roof. It is one of nine armories built in Pennsylvania between 1912 and 1938. The building was also used for Law Enforcement functions and sale expos in recent years.
The Altoona Armory was added to the National Register of Historic Places in 1991.
The Altoona Armory served as an active National Guard facility until the building of the new Pennsylvania Army National Guard Readiness Center for the 56th Stryker Brigade at the Meadows Intersection in Allegheny Twp. Construction on the new facility was completed in 2010.
