If you love natural way of life and if you rather like to watch green landscapes than watching some large settlements constructed of steel and glass then probably there are not much of modern cities which could be attractive to you. However, even those urban areas, so-called bunches of steel, glass and concrete, can sometimes look beautiful.
The most of the world's largest cities are really magnificent during the nights when all those city-lamps and electronic advertisements are giving them unique and glorious shine.
One of such cities is San Francisco, in California. Here we collected a gallery of photos where you can see the attractive side of this colossal city. Those photos were made by respective professional photographer Simon Christen.
