The stadium was damaged by the Gorn when they attacked Pike City during the Dominion War. A recovered piece was displayed at the Pioneer Pub. (ST novel: Articles of the Federation)

Ruth Field was employed as a supplemental hospital for refugees of the Borg Invasion of 2381. (ST novel: A Singular Destiny)
