The range along the western curtain wall dates from about 1480, when the fourth earl remodelled the bailey.
The great hall was the social hub of the castle, where the household gathered to eat.
The now-ruined 15th-century building replaced an earlier hall on the same site, dating from about 1200, although some of the stone dates from the mid 12th century.
The earl would have entered from the south from his connecting private chambers, and people of lower status through the Lion Tower.
Internally, it was split into two aisles of differing width.
Both halls were heated by open hearths, two of which survive from the earlier hall.
Opposite ends of the hall were for opposite ends of the social scale within the castle.
The high end (next to the withdrawing chamber) was for the earl and his family, and the low end (next to the kitchen and other service rooms) for the rest of the household.
In the medieval period, the great hall was richly decorated with tapestries.

The Lion Tower was the entrance to the north end of the great hall.
Above the archway through the tower were displayed heraldic items, symbolic of the Percy earls' power.
The lion at the bottom was the emblem of the earls.
Though now much damaged, above the lion were the ancient arms of the family and the arms of the Lucy family, whose property the Percys had inherited in the 1380s.
As the tower was entered from the bailey, on the right was a doorway leading to the incomplete collegiate church.
To the left was the great hall, and beyond that, withdrawing chambers; to the right were the buttery, pantry, larder, and kitchen.
Immediately north of the kitchen was a postern tower.
Built around 1200, its upper floors were later reused for accommodation.
An entrance of lesser status than the main gatehouse, the gate's position next to the kitchen suggests it was a tradesmen's entrance, used for conveying supplies to the castle.

The square Little Stair Tower was the entrance from the bailey to the withdrawing rooms south of the great hall.
At ground floor level there was a doorway in each of the tower's faces.
Directly south of the east side of the tower was the castle's chapel.
The northern door led to the great hall, and the western door to a cellar under the great chamber.
There are only fragmentary remains of the spiral staircase.
Above the passageway was a single room, of uncertain purpose: it may have been used as another chapel, a guest room, or an antechamber where guests would wait before being admitted into the earl's presence.

South of the great hall was a two-storey building containing withdrawing chambers, dating from around 1200.
Narrow windows opening onto the bailey were original but have since been filled in.
The first floor was entirely occupied by the great chamber, furnished with a fireplace.
In the south-west corner of the room was a door to a small room which was perhaps used as a safe.
The ground floor was used as a cellar, through which the Carrickfergus Tower could be accessed.
The polygonal tower was also accessible through the great chamber at first floor level.
Fitted with latrines and a fireplace, it was an extension of the lordly accommodation provided by the great chamber.
