The ugly Catholic ones are probably all post-Vatican II, when the Modernizers decided to throw away everything from the past and start over. As an example of where this notion can lead, there's a hideously "modern" Lutheran church in Finland, which dates to the independence of Finland early in the 20th Century. It's built into a hillside, and the "walls" are the stone layers in the interior of the hill. With independence, the Finns decided to go "modern" with a vengeance.

I'll go out on a limb and say there's no "probably" about it.
