In those places where our cities now stand, there were once endless steppes, meadows or forests. Or maybe full-flowing rivers or small streams flowed here. And, of course, there was a limitless kingdom of animals and birds. Few people think about it these days - and that's why the works of the Belgian street artist ROA carry so much power. Appearing in ruined and deserted parts of the city, where people try not to look, ROA drawings remind us that those creatures who have not lived here in a long time have found much better use for these places than we do.
