Between 1920 and 1922, veterans of the 307th Regiment ceremoniously planted 16 oak trees in a small landscape at the end of the Mall, just south of the Naumburg Bandshell. Each tree represented one of the regiment’s companies and was marked by a plaque with the names of the soldiers from that company who were lost in the war. Over time, some of the trees died or were removed, but the plaques remain. A large boulder provides an additional memorial, listing all the companies and the names of the members who died.
The Memorial Grove also includes a separate stone memorial dedicated to members of the Knights of Pythias, a fraternal order not affiliated with the regiment, who died during the war.
The 107th Infantry Memorial, located nearby at 67th Street and Fifth Avenue, also honors soldiers who died during World War I.
