It was a great experience for me to attend the worship at the high mass in the Köln cathedral. The cathedral was huge and beautiful. It was impressive how the cathedral survived even after the world war, and Germans did their job so well that they could maintain the structure. I liked that I could listen to amazing organ music during the worship, which is not a common musical instrument used in churches back home, and the burning of incense was also interesting to see and smell. On the whole, it seemed more like the worship leaders were being more serious and holy even though I could not really understand sermon. But still, it was a wonderful experience.
