In the books Edit
In the A Song of Ice and Fire novels, Orkmont was once the seat of House Hoare when they were Kings of the Iron Islands. However when House Hoare went extinct during the War of Conquest, the Targaryens allowed the ironborn to chose which of their Houses would rule over them under the Targaryens. House Greyjoy of Pyke was chosen, so the ruling seat of the Isles was transferred from Orkmont to Pyke.
