Petersburg city brand
full project: http://bit.ly/1nxbrID
Brand strategy: to express the diversity of the city, through the main city function. Petersburg today is "connection", the "bridge": 1. Historically, the city was a "window to Europe", and joined Russia and the West. 2. Actually SPb joined here many shores and islands; 3. It is a cultural center, here there are connected cultures of different countries and peoples, historical heritage and modern architecture.
Bridge, arch is a graphical expression of "connection" and it forms the basis for the logo of the city. In St. Petersburg this module we can see everywhere: river channels, arches, windows, squares - all forms the urban graphic rhythm. This sign forms urban pattern.
All together it forms the city's identity: "Join SPB".
