Like Manhattan, San Francisco is largely trapped by water. Like Manhattan, the city has preserved large swaths of “natural” space (e.g. Central Park, Golden Gate Park) in that hyperdense urban mass. The Mediterranean climate, youth, and topographical preposterousness of San Francisco give it a unique (pardon the neologism) architexture. Looking west from the trees of Telegraph Hill, over Russian Hill and on to the Presidio and the Golden Gate Bridge, the cross-section of environments complement each other. My mind still struggles to see the towers of Russian Hill in the same image as the inhospitable rocks of Marin.
