Standing on the island of Estermont off Cape Wrath, this castle takes its name from the green stone of the surrounding country. Ships passing between Shipbreaker Bay and the Sea of Dorne go by its shores.
House Estermont holds it under Storm's End, and the family is related to the Baratheons by marriage, which has kept it close to the affairs of the greater house despite the island's modest size.
