"Mein Viertel" means my quarter, and refers to the immediate surroundings of your home in a city. For me, it also refers to where I know the people I meet on the street, where I go to the market, buy groceries and have my post office. It also includes a few broader landmarks which I relate to. Here a few snapshots of my quarter in Frankfurt am Main.

A residential road leading to the European Central Bank, close to the Main river.
