Reading Between the Lines: Belgium’s Church That Disappears Before Your Eyes

Quick Facts: Work: “Reading Between the Lines.” Artists: Gijs Van Vaerenbergh (Pieterjan Gijs and Arnout Van Vaerenbergh). Location: Borgloon, Belgium. Year: 2011. Material: 100 layers of stacked, perforated steel plates. Effect: From most angles, reads as a solid church. From others, becomes nearly transparent. Commissioned by: Z-OUT, a Belgian landscape art initiative.

From a distance, it reads as a church. A simple, familiar silhouette against the Belgian sky. Walk around it, or shift your angle slightly, and it dissolves. The walls become transparent, the floor becomes sky, and the whole structure disappears into the landscape it seemed to define. “Reading Between the Lines” by Gijs Van Vaerenbergh is one of the most quietly extraordinary pieces of architectural sculpture made in the last two decades.

How the Illusion Works

The structure is made of 100 horizontal layers of perforated Corten steel, each cut into the profile of a Romanesque church. Stack them closely enough and the solid form appears. But the perforations and the gaps between layers mean the building is never quite solid. Change your viewing angle by a few degrees and the steel plates align with the gaps between them, making the entire church effectively vanish.

Why It’s Sited in Borgloon

Borgloon is a municipality in the Flemish fruit-growing region of Belgium, a landscape of orchards and gentle hills. The church form connects directly to the region’s heritage — rural Belgium is dense with Romanesque churches. Placing a ghost version of that form in an open field is an act of dialogue with the landscape, not just optical trickery.

What Makes It Linger

Most optical illusions work once. This one doesn’t. The experience changes with time of day, weather, season, and viewing position. In winter, when the steel rusts to a deep orange against grey sky, it reads completely differently than in spring, when orchard blossoms compete for your attention. It rewards returning, which is rare for any work of art, let alone one made of perforated steel in a Belgian field.
