This church on the outskirts of Vienna astounds with its mad Lego-like architectural exterior, which is made with no apparent rhyme or reason. Designed by sculptor Fritz Wotruba, the decidedly cubist result consists of 152 asymmetrically arranged concrete blocks—as small as 0.84 sqm and as large as 64 sqm, weighing from 1.8 to 141 tons—stacked on top of one another.

Wotruba Chuch was built between 1974 and 1976. It’s a modern manifest for art, architecture and spirituality—as such, the community forewarns on the church’s website: “Attention, visiting our church may change your future life.” Pray it does.
