Fictional Mereen and Split have something in common: they were both slave cities. Diocletian’s palace was built by slaves during Diocletian’s times, and inside the palace there is “Kill the Masters” street where slaves ambushed the slave masters. Furthermore, the basement of the palace is place where dragons were locked when they were out-of-control teenagers. Along with game of thrones locations you will also learn about history of Split. And bear in mind – history is often more brutal than fiction.
