A shoutout to Martina to say "Hey, I visited your hometown", and I think you should be proud to able to call it home. In fact, Košice is a lovely town center. And for tourists: easy access from hotels, parking, shops, lovely gardens planted around the centre, fountain, a big Gothic cathedrals, many good bars and restaurants - my picture shows it just shows an ideal town. That's probably what the people who want to nominate this as world heritage had in mind too. Sorry, a little overeager. The whole core thing also doesn't seem unique enough and if it would be a front-runner for this concept in any way that would make it very, very niche. I'm guessing though, that it was not started in in Košice and either a similar style or taken from other countries (by crusaders?) that it was built this way.

Do visit Košice for it's a wonderful town but don't expect a world heritage site, ever.
