In 1919, soldiers of the Boal Troop returning from the war erected a monument on the Boal Estate dedicated to their fallen comrades. In the 1920s, other units of the 28th began erecting their own memorials, and began to refer to the area as a "shrine". In 1931, the Commonwealth of Pennsylvania purchased the site, and in 1969 the Pennsylvania Military Museum was opened. By 1971, memorials to most of the units of the 28th that served in World War I had been erected, and in 1997 a World War II memorial was dedicated at this site.
