The oldest and outmost building at Pyke, the round and tall Sea Tower is located on a crooked pillar. Its base has turned white from salt spray, and its upper stories are green with lichen. The nightly watchfire has turned its jagged crown black with soot. The banner of House Greyjoy flies over the building.
The Sea Tower is accessible from the Great Keep through three increasingly narrow bridges. Its door is grey wood studded with iron. The solar of the Lord Reaper of Pyke is found in the Sea Tower. The halls of the Bloody Keep are larger and better furnished than those of the Sea Tower, but both buildings are still cold and damp. Howling wind and crashing waves can be heard from the Sea Tower.
A Clash of Kings
Instead of staying in the Sea Tower upon his return to Pyke, Theon Greyjoy is given a suite in the Bloody Keep. Theon then meets his father Balon, Lord of the Iron Islands, in his solar within the Sea Tower. Balon burns the letter from Robb Stark in a brazier.
