4. Battle Arena: Oberyn Martell v. The Mountain

The shocking season four finale, where The Mountain kills Oberyn Martell, the Dorne prince fighting to defend Tyrion’s honor, is filmed just outside Dubrovnik at the abandoned Hotel Belvedere, destroyed during the Croatian War of Independence. The crest in the “arena” was added by the Game of Thrones set designers and remained after filming (as seen above). See more photographs of the Hotel Belvedere here on our previous explorations of this abandoned site.
