In Kraków Old Town? Around 99% (also it is UNESCO World Heritage Site and so on) https://en.wikipedia.org/wiki/Krak%C3%B3w_Old_Town https://en.wikipedia.org/wiki/Krak%C3%B3w_Old_Town https://www.openstreetmap.org/#map=17/50.06160/19.93683 https://www.openstreetmap.org/#map=17/50.06160/19.93683 And "rebuild most of city due to tourism" has its own costs. I would prefer to simply have less of a tourism. For start remove nasty parts like stag/hen parties and people traveling here because alcohol is cheap, they are anyway providing only worst kind of jobs. Maybe make city famous that being drunk, yelling and vomiting during night causes you to be stopped by police? And dumb parties of "rent a roofless car, drive around and be loud during middle of the night" type gets ruined?
