It is a real huge Cathedral. I wonder what the colourful shapes on the window are. I think I have seen them in a church as well.
Someone told me that Prague's arthitecture is like Italy. Therefore, I should visit it :)
Thank you for sharing the inside of the church with us.
It´s called stained glass ;) https://en.wikipedia.org/wiki/Stained_glass You can find this kind of decoration in many old churches in Europe. I know you said it´s not easy to get the visa for you but I hope you will still make it here one day :) Greetings to Turkey!
