This is a picture of a Strasbourg canal, taken from the Grande Île in the Petite-France neighborhood. With all the bridges and blacktop you’d never realize this was an island – and I never realized it either until I looked it up on Wikipedia.
This is also a “best kept secret” of Strasbourg, since it is only just a few blocks from the main train station (Gare Central) in Strasbourg, but in a direction opposite to where most tourists head when they descend upon the city. It is amazing what things you can miss – or find – by simply walking in the wrong direction.
