As the name implies, the Crownlands are where the King of the Seven Kingdoms rules from the Iron Throne. It's located on the eastern coast of Westeros, north of the Stormlands, and south of the Riverlands.
Notable locations:
- King's Landing: Obviously. King's Landing is the location of the Red Keep and is where the king lives. It's also where Ned Stark is executed in season one, where Joffrey Baratheon is assassinated in season four, and where like, everyone dies in season six when Cersei blows up the Sept of Baelor. Not exactly the happiest of places.
- Dragonstone: An island off the coast of King's Landing, Dragonstone is separated from the city by Blackwater Bay. It is once the home of the Targaryen family, but in Game of Thrones it's where Stannis Baratheon is camping when we first meet him. This is also where he plans his attack on King's Landing in the Battle of the Blackwater. The teaser trailer for season seven hints that Dragonstone is where Daenerys first lands when she arrives in Westeros. How fitting.
