We visited one of the three major churches in the United States and we were not disappointed. This is not only an architectural marvel, but also an impressive display of magnificent interiors, stunning decorations everywhere, and a very unique painting technique. You must go to the gift shop, do not miss the underground church, which is the second place to worship, it also has some very typical characteristics, especially the treasure house preserved behind the iron gate. We spent an hour and a half visiting here, and experienced it carefully inside and outside. But you can also complete the visit in a shorter time.
