Luna Romana was a theme park on the Moon. By the time that the Fourth Doctor and Romana II visited it had been long since abandoned. They both encountered Stoyn at the park. It contained areas based on Ancient Rome, Wild West America and a reconstruction of the Battle of Reykjavik. (AUDIO: Luna Romana)
