This was the center of San Francisco in pioneer days, deeded for public use January 3, 1850, during the administration of John White Geary, first mayor and postmaster, and later Governor of Kansas and Pennsylvania. The name originated in 1860 when public meetings were held here in support of the Union.

1971 register text, presented as a historical document. It uses the period's terms for Native people; the state's landmark listings still carry most of this wording, and the California Office of Historic Preservation maintains the program's current texts.

Many of these plaques have since been recast or their texts revised. The California Historical Landmarks program and its current texts are maintained by the California Office of Historic Preservation. California Office of Historic Preservation ↗
