Serbia is not a real tourist destination, but it faces the same situation you wrote about, the decades-long population migration from the countryside to the big cities.

Believe it or not, there was (and probably still is) a similar situation here, where you could buy a whole village for 5-10K EUR in some rural areas of Spain... The government took some measures and offered the RE for young people for a cheap price, but with a commitment to stay there for X years... The problem isn't solved completely, but it looks like we (and other locals) will go to those villages as we will not be able to pay the rent... lol... So, that problem will be solved by another problem... hahahaha 😂

With an additional burden on RE, which you in Spain probably did not feel. Migration of people from Ukraine and Russia.

Yeah, a similar problem is in Hungary with migration from war-affected countries... We have people from Russia and Ukraine here in Spain too, but I doubt that they are from the same "class" as those at your place... These here are with BMW, Mercedes, Jeep, and other huge cars... Fit in with wealthy Norwegians and Dutch people...

PS. In addition to Spain, Italy also has many tourist attractions, and Rome (the old city center) is literally an open-air museum - we commented on that a few years ago when we were on a tourist trip.

When you remind me of Rome, I will be that "tourist" as I want to go to visit it... lol... So, we are also part of the problem, too! 😃
