Abram R. Woolley Tablet

The Allegheny Arsenal was one of the most important armories in the United States during the Civil War. This tablet was placed on its walls when the Arsenal was erected on this site in 1814. The initials reference Abram R. Woolley, the first commandant, with the seventeen stars encircling the border representing the number of states in the Union at the time.
Cannon

This 9-inch Shell Gun was made in 1855 by the Tredegar Iron Works in Richmond.
Cannons of this type were used in the armament of battleships for shoreline defense. Markings on the barrel indicate that it was fired 1,681 times, which may indicate it was a test gun and not used in combat.
Soldiers & Sailors Memorial Fountain

Arsenal Park, made up of the land that was once the historic Allegheny Arsenal, was only two years old when this fountain was directed to commemorate those who had served in the War of 1812.
The dedication was attended by newly-inaugurated President Taft, who gave a speech. The fountain was originally placed in the southwestern section of the park, and delivered water from a natural spring to a round basin in its front. It was later relocated and the basin was removed.
