Intrusion traces the entanglement of migration in cartographies. The project juxtaposes Google Street View screenshots of the northern French city of Calais, taken between 2014 and 2018, with their updated 2019 versions, each on a double-page spread. The earlier images show numerous refugees, tents and camps; after Google's 2019 update no people are visible, and newly erected, martial border fences appear instead. Whether the removal of the traces of the crisis from the internet was politically motivated or just part of a standardised update process remains unanswered, even after an inquiry to Google.
