Allegheny County provided free burials for approximately 3,000 veterans over 28 years. There are no raised monuments. Built of limestone and rubble excavated from a quarry within the Allegheny Cemetery, this pleasant compromise between Classical and Modernistic is typical of its time.
Bronze cannons from the Civil War period stand before the Soldiers' Memorial, which the Allegheny Cemetery Historical Association restored.
In 1937, the cemetery built the Soldiers' Memorial overlooking the central area of military graves. It combines classical and Modernist architectural styles. Many of the graves memorialize soldiers from all wars.
