In 2014 when I was in Albania, I noticed something interesting. While 60% of the Albanian people are Muslim, 10-15% of the people are Catholic and 10-15% belong to the Orthodox Church. The Muslims are not religious in the slightest. It seemed that the Christians were more devout. Either way, I could tell the difference between the Orthodox and Catholic churches with ease. They simply had different architecture. The Catholic churches looked more like a Church one would find in Italy or France and the Orthodox Churches looked more like the churches that I had just seen in Serbia a few days prior.
