Jubilee Church (Rome)
Church of Santa Monica Spain
Christ Hope of the World (Austria)
I did plan to comment on my findings but I am afraid I was unable to find the words apart from to say that this is not a joke and that these buildings really do serve as Catholic churches.
If you find this topic interesting, I recommend the following book.
No Place for God: The Denial of Transcendence in Modern Church Architecture. Below is a short extract which quite possibly says it all.
The modern age has witnessed the construction of the most banal and uninspiring churches in history. The attempt to create a church architecture that would meet the needs of the age has resulted in churches that are unfit for any age. Contemporary church buildings, as well as being the ugliest ever built, are also the emptiest.
Many atheists used to say that whatever they felt about religion, it was impossible not to admire church architecture. But now there is hardly a Catholic who can admire (modern) church architecture.
