An old but not particularly strong castle, Deepwood Motte is located in the wolfswood at a wide, rounded hill with a flattened top. The castle's cavernous longhall sits atop the hill and has at one end a watchtower rising fifty feet higher, the tallest object this side of the northern mountains. Wooden steps lead to the bedchamber of the Master of Deepwood Motte, and the keep has an exterior stair.[3]
Below the hill is a bailey containing stables, paddock, smithy, well, and sheepfold. These are defended by deep ditches, a sloping earthen dike, and a log palisade. The kitchens are located in Deepwood's inner yard, and the castle also has a godswood and a cellar.[3]
Deepwood's mossy, wooden outer walls make an oval about the hill and are protected by wallwalks. Gates located to the north and south each have two square wooden towers, with moss growing on the southern towers and palisade.[3] Deepwood has at least one postern gate, located on the eastern side.[3]
East and west of Deepwood are fields of oat and barley.[3] North of the castle Motte lie tidal flats[1] leading to the Bay of Ice. Deepwood is five leagues south of the Bay of Ice[3] and one hundred leagues (three hundred miles) northwest of Winterfell.[4]
