Religion
There were quite a few mosques and churches. The churches looked to me (a remarkably unreligious person) a lot more like the mosques than I was expecting. Some of the Orthodox Christians were praying loudly over loudspeakers at assorted times of day. Until someone corrected me, I had assumed they were Muslims praying.
I also saw religious services taking place out in an open area under some trees.
Because of my short stay, I did not have the opportunity to participate in any religious services. I would recommend that everyone, even if you are not normally religious, seek out a service to attend.
