between the lines

Located on the grounds of an orchard in Borgloon near Liège, the Doorkijkkerk (See-through Church) was installed in 2011 as part of a public arts campaign to urge thinking about open spaces through negative space and the silhouette of architecture. The weightless structure is comprised of one hundred metal plates supported by two thousand columns. Depending on the angle of the viewer, the perspective of the church shifts from nearly solid to vanishing thin and wan against the sky.
