San Francisco is a city where the past flows fluidly to the present. Where cable cars are something to ride on, not just to look at. Where Edwardian flats are lived in. In San Francisco, the ghosts of the past don’t leave, not really — they stay with us, resonating, creating a joyfully eclectic tapestry of all the city’s eras. San Francisco Centre, like the city itself, is living history.We embrace our heritage, but we’re not just looking backward. There’s no need to be nostalgic for the past because, after all, it is still with us.
