The exhibition catalogue Frontières Invisibles features the work of more than seventy European artists. The exhibition of the same name in Lille is an invitation by lille3000 to consider the enlargement of viewpoints in a changing, elastic, "XXL" Europe, moving further towards the East and full of diversity. Twenty years after the fall of the Berlin Wall, it appears essential to learn more about the dynamism of these contemporary artistic and creative scenes which cross without taboos the old lines of demarcation and to discover a new vision of Eastern and Central Europe, between the geopolitical and the geopoetical.
