When I was a kid there was a country called Yugoslavia. But after a terrible war twenty years ago, the regions split up into different countries. Nowadays there is Croatia, Slovenia, Bosnia-Herzegova, Montenegro and Serbia. Montenegro only gained its independence in 2006.
We spent a lovely day wandering round walled cities, some of them BC. Here are photos from a city called Kotor. It sits on a bay which is a natural fjord. I loved the feel, it had elements that felt a teensy bit alpine.
