I stop in the St. Louis Basilica a few times a year. I was up there last week and dropped in for about 30 minutes. It is an amazing place. It is the largest mosaic structure in the world and the tiles took almost 90 years to complete by the same family. Three generations.
It is a wonderful place to get grounded. I like to lay on the pews and stare up at the ceiling
This first photo is of the front of the building. The next photo is of the main dome in the center of the church. The third photo is of the main alter.
If you are into art or architecture try to get there. You will be amazed. You could pretend to be in Europe.
