Flushing Armory, ca. 1910.

Designed by George Heins (known best for his early subway station architecture with partner Christopher LaFarge), and completed in 1905, the Flushing Armory was originally the home of the 17th Separate Company. The crenelated building was nearly identical to Hein's designs for three other armories in upstate New York. While this design did not break the mold of New York City armory styles (nearly all of the 19th and early 20th century armories in the five boroughs are castle-like), Heins did prefer octagonal towers to round ones.

The 17th Separate Company was founded in 1876, and between 1894 and 1905 occupied a wood and brick armory on Roosevelt Avenue. The 17th Separate became Company 1 after the First World War and moved to Brooklyn’s 14th Regiment. Other military units were housed here throughout the 20th century. Eventually turned over to the city, the old armory served as a homeless shelter (a common reprogramming of these large spaces) and a gymnastics center. Today it is the headquarters of the NYPD’s Queens North Taskforce.
