There's so much to say about the development of San Francisco around Portsmouth Square, the city's oldest center point, so I'll start small.
This is a bridge element to the Chinatown Hilton. It sits on the overpass above Kearny Street connecting The Square and the former site of The Hall of Justice.
Today, The Hilton Chinatown is a Brutalist Monument of The 1970s, barely concealing its middle finger to the surrounding neighborhoods.
The redevelopment of the blocks once known as Little Manila, by the Transamerica Pyramid, are evolving quickly into a new district after two decades of inertia.
This element is meant to symbolize Chinatown. It may, in the sense that you can't see all sides of it at first glance, even as you think you see through it.
