Oakenshield
Escudo de Roble
Oakenshield is, in truth, two unrelated places that happen to share a name. One is among the Shield Islands, the chain that guards the coast of the Reach west of Highgarden, and it serves as the seat of House Hewett. The other is an empty Night's Watch stronghold on the Wall, sitting just west of Castle Black.
No one has explained whether the two places are connected in any way or whether the name was simply reused by chance on opposite sides of the map. The island, at least, has sent men and ships into the history of the Reach more than once.
Chapter 1
The Hewett island

Oakenshield is one of the Shield Islands, that string of small lands facing the sea just west of Highgarden. It is the seat of House Hewett, and on maps of the Reach the island and the family end up meaning almost the same thing.
