The park sits on property originally part of the Entwistle family homestead. James Entwistle – the first settler in Carnation – arrived in 1858. A collaborative effort by the Valley Men’s Club and David Entwistle (James’ son) generated the idea for Valley Memorial Park in 1945. Volunteers constructed the park between 1945 and 1949 using donated materials. In 1947 a committee including representatives from the Men’s Club and the American Legion voted to install a World War II monument subsequently dedicated on Memorial Day 1949.
King County owned and operated Valley Memorial Park from the late 1940s and then deeded it to the City of Carnation in 1982. In additional to the monument, the park includes a skateboard bowl, tennis courts, and a picnic area.
