aren't all churches this transparent?

From Diply:

Gijs Van Vaerenbergh, Belgian architects, built a church that is see-through. They called it Reading Between The Lines. It has 100 stacked layers of steel. It was designed specifically so that the

 landscape around can always be visible through the church, making the church both visible and absent in the world around it.

It's a stunning design because depending on the angle you look at it from, it looks completely different. From one view it can look like a solid church, whereas from another angle it will look hardly there at all.  link
