Navy Yard in Southeast Washington in Washington, District of Columbia — The American Northeast (Mid-Atlantic)
The Washington Navy Yard
Rebuilt after the War of 1812, the Yard continued to construct ships, but by the 1850s its primary function had evolved into ordnance production. The engineering genius of Lieutenant John Dahlgren (twice commandant of the Yard) nurtured this development, and in 1886 the Navy concentrated its ordnance work at what came to be known as the Naval Gun Factory.
In addition to ordnance, other notable United States technological achievements at the Yard include: the first marine railway (1822), the first ship model basin (1898), the first successful shipboard catapult (1912), and a wind tunnel (1914).
Expanding to meet the needs of a growing fleet during World War I, the Yard designed and manufactured the Navy's first 16" guns as well as the innovative U.S. Navy Railway Batteries that served in France. Mobilization for World War II resulted in further expansion. While the Yard administered the program for production of naval ordnance by private industry, it directed its own efforts on the design and testing of new weapons and the production of 16" guns.
When industrial production ceased in 1961, the facility became a supply and administrative center. Once again designated as the Washington Navy Yard, this historic complex has become the ceremonial quarterdeck of the Navy.
Erected by U.S. Navy.

3. The Washington Navy Yard Monument
Note the iron "eprouvettes" and muzzles of iron cannons at the base of the flag pole. See photos below for more on the eprouvettes. The iron cannon were old types discarded by the Navy, but used here as bases for flagpole cleats.

6. Leutze Park, the Washington Navy Yard's ceremonial quarterdeck
View toward Latrobe Gate, across the park (named for RAdm. Eugene H. Leutze, Commandant of the Yard, 1905-1910) from the National Historic Landmark plaque. The Washington Navy Yard Marker is among the trees near the flagpole.

8. Eprouvette Mortars and Iron Guns
Early black powder was often inconsistent in its strength and had to be tested before being used. These three iron eprouvette mortars were used to test samples of new lots of artillery powder. Around the flagstaff base are four iron guns, filled with concrete and buried breechdown. As new cannon were introduced, many old ones were used as pier bollards, gate posts, or - as in this case - bases for flagpole cleats.

9. The Washington Navy Yard "Watch Box"
Manned by Marines, this small building was part of the sentry post that helped secure the 8th Street entrance to the Washington Navy Yard until around 1905 when it was removed to the Navy's Proving Grounds at Indian Head, Maryland for another century.

11. An Eprouvette
The eprouvette was a variation of the mortar. As seen here, construction was a simple "cup" on a fixed bed. Elevation was exactly 45 degrees. Based on that fixed elevation, the strength of the powder could be calculated based on the distance a 24 pound shot was propelled by a single ounce of powder. The range was expected to exceed 225 yards. Good powder propelled the shot to over 300 yards.
The eprouvette fell into disfavor as it was discovered black powder strength increases exponentially as quantity is increased. Furthermore, the qualities of slow burning powder, which worked much better in long bore cannon, could not be tested in the small mortar.

12. The Middledorf Building and Historic Commandant's Office
The U.S. Navy's oldest active office building, constructed 1837-38, renovated 1993. Note some of the Yard's extensive collection of historic iron ordnance on display in the foreground. On the right is a "Stockton Gun" which once armed the USS Princeton. In the center is a Brooke 7-inch Rifled Cannon from the CSS Tennessee, made famous for actions at the Battle of Mobile Bay. On the right is a 10-inch Brooke Smoothbore from the CSS Columbia, captured at Charleston, S.C.
