Curtain walls extend as a total barrier, often in a broad perimeter around a castle, here going up the mountain as an escape for an entire town, there, in the back.
Why need such extensive wall structures apart from the main walled town. The separate curtain wall is a familiar sight in the Balkans, going up the mountains. The curtain wall was needed because of the location of the town, at roadways and ports invaders used through the years. Occupation after occupation. With mountains as a backdrop, the city could be better defended, but. Kotor still has been in many hands - warfare upon warfare.

Kotor - look closely at the mountain to see the curtain walls going up the side, another defense.
At Kotor, as in places in Croatia (especially Ston, see Croatia Road Ways, Ston post), you can see curtain walls going most all the way up a mountainside, with a large fortress at the top. These serve as another line of defense, if the the city walls are breached the population flees up the mountain. There is refuge there, better than below.
Kotor is a UNESCO World Heritage site. See whc.unesco.org/en/list/125; and thesalmons.org/lynn/wh-montenegro.
There are also palm trees, just as there are in the warm parts of Scotland even, and the old buildings. See the old town at www.photo-montenegro.com/home. Go further to these notations if that is helpful: php?akcija=rezpret&fKategorija=Kotor&fPodKategorija=Old+Town. Kotor was less damaged by invasions than many coastal towns, I understand. See www.matf.bg.ac.yu/konferencije/kotor/.
There are many ATM's, but you may find that only selected cards will work, and the money is not Euro. We ran into five currencies this trip - different in Croatia, Slovenia, Bosnia, Montenegro and Serbia. Some will accept Euro, but we preferred to use the country's cash and withdrew some for each day.
Before you leave US: You should alert your credit card or debit card places that you will be in specific countries so they will not block your getting cash. We did that ahead of time, and still found that one card could not be used. Much fraud out there.
