The ugliest is the Our Lady of the Angels cathedral in Los Angeles.
However, last year, the Our Savior Church, a beautiful Catholic house of worship built in the Italian Romanesque style, opened a block north of USC.
My parents’ church is currently undergoing renovations. The Masses have been moved to a very plain cinder block auditorium in the interim. Many have commented that this seems to have brought the Mass closer to the people. Whether it’s fewer distractions or a more intimate setting, hard to say.
Yes, that is a nice church. I think the new San Francisco cathedral offers some competition to the one in LA.
I drove by that church near USC about 6 weeks ago and showed it to my kids after touring USC. It really is lovely.
