There are numerous churches in our world, in different parts of the world. All they are great, but some of them are truly stunning and can for real take away our breath. How many pilgrims and tourists visit these sanctuaries just in one year impossible to count, but, I believe, people from all over the world come to see these beauties. Some want to touch holy place, some are interested in old charming architecture, some hiring guides in order to hear the history of any of them.
Agree, they are amazing, and just imagine how they were built, how many artists worked on all these paintings, frescos. It is hard to imagine how it was done so many years ago without any modern technologies. But architects and artists created true miracles. You still have not been in any of them? Hurry up, it worth to enter these sanctuaries, and they really are taking away the breath.
