Plaque text:
Union Square
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.
