Kotor might be the most gorgeous part of Adriatic Sea, beautiful town in the terminal of fjord. The history date back to 168 BC, there Roman Era. The first fortress built in Middle Age by Justinian I, in the list of UNESCO. It's the terminal of the fjord, the sea is more peaceful than usual.
The old town is not big, but somehow with good vibe, it was kind of low season not so many tourists on street. There are some hidden places to walk around, one wall really surprised me, I was walking along the city wall and got on a stair, it was there on the side seems abandoned ruin, not obvious...but I noticed it.
