These are memorial monuments  within the Queens Village Veterans Plaza, located at the intersection of Springfield Boulevard and Jamaica Avenue in Queens Village.  These monuments are in honor of the American soldiers who fought and gave their lives for our country during the World War II.  “This land was acquired in 1927 and it was assigned to Parks in January 13, 1932.”  The Plaza contains seating areas and a covered stage along with the monuments.  It is a very peaceful area that I often visit and enjoy nature and all of the surroundings,
