Castle Black is an ancient stronghold and is the headquarters of the Night's Watch. The castle is situated along the Wall between Queensgate to the west and Oakenshield to the east, near the center of the Wall, at the northern end of the kingsroad. The village of Mole's Town is located half a league to the south along the kingsroad.
Despite there being nineteen strongholds along the Wall, Castle Black is one of only three still manned by the Night's Watch, the others being the Shadow Tower and Eastwatch-by-the-Sea. The castle once held over five thousand men, but it now currently holds about six hundred brothers.

Castle Black is not a true castle, as it has no walls to defend it to the west, east, or south. Only the Wall stands to the north. It consists of several stone towers and timber keeps. Beneath the keeps and towers, there is a series of subterranean passages called wormwalks which connect all of the buildings. They are rarely used during the summer, but in the winter it is the only way to travel to different parts of the castle.
Castle Black has only a small sept and no godswood. Men who follow the old gods have to travel beyond the Wall, into the haunted forest, to a small grove of carven weirwoods left by the children of the forest, to swear their vows.
- The Lord Commander's Tower, also called "Commander's Keep", is where the Lord Commander's quarters are located.
- The King's Tower is a 100 foot tall round tower with merlons atop it, overlooking the gate and the foot of the wooden stair leading up the Wall. The entry door is made of oak studded with iron. Although it is reserved for honored guests and named for kings, no king has visited the tower in over a hundred years.
- Hardin's Tower has a broken battlement, from which stone has spilled into the yard below. It has a severe lean.
- The Lance is the tallest tower at the castle, though only a third of the height of the Wall. It is slim and crumbling.
- The Tower of Guards is the strongest of the towers. It lies next to the kingsroad and the Wall, and guards the wooden stair.
- The Silent Tower is a tower at Castle Black.
- The common hall is a great timbered keep where the brothers take their meals. Crows nest in the rafters.
- The rookery is the nesting place of Castle Black's ravens. Consequently, the maester's quarters are located in a stout wooden keep beneath it.
- The armory is where the equipment for weapons practice is kept. Donal Noye forges weapons and armor here.
- The old Flint Barracks is where most of the brothers reside.
- The vaults, located underground, contain food stores and the library. The library contains records and old books that even the Citadel does not have. Amongst other topics, it covers drawings of the faces in the weirwoods, the language of the children of the forest, and scrolls from Valyria.
- The Shieldhall is a feast hall of dark stone. In years past, when the Night's Watch was much larger in number, its walls had been hung with rows of brightly colored wooden shields. When a knight took the black, his shield would adorn its wall and he would take up the plain black shield of the brotherhood.
There are a series of tunnels underneath Castle Black called wormwalks or wormways, which connect the various keeps and towers. These tunnels are mostly used during the winter, when the cold and snow, sometimes forty or fifty feet deep, make it impossible to travel above ground. The large library of Castle Black lies along one of these tunnels.

- The gate guards the tunnel through the Wall, which is long, twisting and narrow. Three iron gates block the inner passage. Each of these gates is locked and has a murder hole above it. The outer door to the tunnel is solid oak, about nine inches thick.
- The great switchback stair climbs its way up from Castle Black to the top of the Wall. It is made of wooden stairs, anchored by huge beams frozen into the Wall itself.
- A winch elevator is used to take supplies and men up to the top of the Wall. It is an iron cage attached to a winch to allow it to ascend and descend the face of the Wall. It can hold ten men or an equal amount of supplies. It is located near Castle Black's well.
- Facilities on top of the Wall include a small warming shed for the men on watch located next to the crane.
A Game of Thrones
Jon Snow and Samwell Tarly are trained by Ser Alliser Thorne as recruits of the Night's Watch at Castle Black. Tyrion Lannister sleeps in the King's Tower during his visit to the Wall, while Jon sleeps in Hardin's Tower. Jon and Sam swear their vows at the nearby godswood north of the Wall and are sworn in as new brothers of the Watch. The bodies of Jafer Flowers and Othor, rangers killed beyond the Wall, reanimate as wights at Castle Black. The Lord Commander's Tower burns down during Jon's fight with undead Othor when it tries to kill Lord Commander Jeor Mormont.
A Clash of Kings
Two hundred men from Castle Black accompany Lord Commander Mormont during the the Great Ranging north of the Wall. Maester Aemon remains at the castle because of his age. Samwell Tarly reads a report about a brother leading a ranging to the Frozen Shore before the Conquest in the library.
A Storm of Swords
Jon returns to Castle Black after being wounded by wildlings south of the Wall. Jon and Donal Noye fortify Castle Black as best they can in anticipation of Styr, Magnar of Thenn. Styr's wilding raiders are defeated in a fire trap at the wooden stairs of the castle.
Mance Rayder attacks the Wall with multiple waves of wildings during the Battle of Castle Black. Jon leads the defenders atop the Wall while Donal protects the tunnel through the Wall. After the death of Donal, Aemon tells Jon that he must lead Castle Black until its garrison returns. Jon is sent as an envoy to meet with Mance north of the Wall. As they converse, the knights of King Stannis Baratheon appear and rout the wilding host.
In the aftermath of the battle, Sam finds the common hall burned to the ground and the wooden stair a mound of broken ice and scorched timbers. Stannis occupies the King's Tower, while the Lance, Hardin's Tower, the Grey Keep, the Shieldhall, and other buildings are also crowded with men. Jon Snow is selected as the new lord commander to replace the deceased Jeor Mormont.
A Feast for Crows
Samwell searches in Castle Black's library for information about the Others. Sam learns from Lord Commander Jon Snow that he must escort Maester Aemon to Oldtown and then train at the Citadel to become Castle Black's new maester. Because Stannis Baratheon has claimed the King's Tower, and the Lord Commander's Tower has been gutted by fire, Jon Snow establishes himself in Donal Noye's modest quarters behind the armory. 
A Dance with Dragons
Castle Black hosts the army of King Stannis. Jon Snow executes Janos Slynt for disobedience, while Melisandre burns "Mance Rayder". Jon allows thousands of captive wildlings to cross through the Wall to Castle Black, much to the consternation of some members of the Night's Watch. The officers worry there will not be enough rations for the additional mouths. Stannis departs to recruit the northern mountain clans, although Melisandre remains at Castle Black. Some wildlings are recruited by Jon to help the Night's Watch defend the Wall.
Queen Selyse and her Queen's Men stop at Castle Black on their way to the Nightfort. Alys Karstark arrives seeking refuge and is married to Sigorn of Thenn by Melisandre. Jon has Alys's relative Cregan Karstark imprisoned in an ice cell. Val brings Tormund Giantsbane and his four thousand wildlings to Castle Black, but Bowen Marsh and the mountain clans disapprove of the wildlings settling south of the Wall.
Lord Commander Snow agrees to disperse the wildings amongst the previously abandoned castles along the Wall. Jon receives a belligerent letter from Ramsay Bolton and, choosing to break his vow to the Night's Watch to remain neutral, decides to go to Winterfell to confront Ramsay. As he prepares, the giant Wun Wun kills one of the queen's men, Patrek of King's Mountain. While Jon is trying to make sense of the situation, he is attacked by Bowen and other members of the Night's Watch.
