Game of Thrones filmed at Grjótagjá, Mývatn. The lava cave with the hot spring; bathing is no longer permitted. On screen it's Beyond the Wall.
Probable Named in published production coverage; the coordinate is the place itself, checked against a gazetteer. This is an area, not a spot. The coordinate is its middle, so use it to navigate to the place and not to line up a shot.
Venture keeps every scene location on one map, sorted by how far you'd have to walk. Open it in Mývatn and it tells you what was shot around you, how to get there, and whether you can actually go in.
