This was the first “Social Sofa” in Zaanstad. It was officially unveiled in 2020 by the counsil of the province of North-Holland and Heijmans Builders, who jointly commissioned it to commemorate their (not altogether seemless) cooperation on the renovation of the adjacent Wilhelmina lock. That is why the word “Wilhelminasluis” is featured on the back of the sofa. It was designed by local artist Olivier Rijcken and it took him and a team of volunteers some 350 hours to complete the mosaic work (30.000 pieces).
