10,000 Steps, a historic walking tour created in 2006, explores downtown Oakland’s historic parks. These parks—Jefferson Square, Lafayette Square, Madison Square, and Lincoln Square – each occupy only one city block. Walking this "Invisible City" is downtown Oakland’s first permanent self-guided walking tour. By following engraved sidewalk markers, walkers can explore this historic city. Oakland’s first city plan, drawn in 1853 by Julius Kellersberger, was framed by seven oak-filled squares. Today, five of these squares continue to support the diverse communities who live nearby. Walking the Invisible City will lead you to these historic parks and vibrant neighborhoods near Oakland's Chinatown.
