The name "Schengen" originates from a small town in Luxembourg. In June 1985, seven European Union countries signed a treaty to end internal border checkpoints and controls. More countries have joined the treaty over the past years. At present, there are 15 Schengen countries, all in Europe.
The 15 Schengen countries are: Austria, Belgium, Denmark, Finland, France, Germany, Iceland, Italy, Greece, Luxembourg, Netherlands, Norway, Portugal, Spain and Sweden. All these countries except Norway and Iceland are European Union members.
