At the beginning of this year, at the invitation of Museum IJsselstein, de Onkruidenier started an eight-month research project into the traces of the sea. Since the middle of the 19th century the influence of ebb and flow has hardly been felt in IJsselstein. The painting of De IJsselpoort of the city of IJsselstein, as seen from the barony of IJsselstein by the artist Jan Weissenbruch (1822-1880) previously provided us with fine inspiration. The research has led to a new work the Peilwachter which has been installed on the Bolwerk, an outdoor location opposite the museum. The work can be seen as part of the exhibition on empathy: ‘No man is an island.’ with several works spread across IJsselstein.
