Visby, land of peaceful vikings ...

... and holiday island for most swedish. Visby, in Gotland, has an excellent state of preservation, with lots of amazing churches and medieval buildings. It seems that people in Visby tended to open the doors to invaders, so they did not have the urge to conquer and destroy. Sort of like Ankh Morpork :D The symbol of the city is a lamb, so go guess...
