Although I did not take a tour, I did attend Mass. The architecture of the building is beautiful. Having the opportunity to hear the pipe organ provided an environment of solemnity and serenity.
Historic, majestic, and of course spiritual. After Mass take the time to look around at the stained glass, side alters, etc. You won't be disappointed.
You can enter and visit for free. The building looks great from outside, but the inside is not very impressive except for the dome. Worth a quick view if you are in the area.
