The five storey tower is simple in design and positioned on a steep and high, jagged
roche moutonnée, making approach for attackers difficult. The ground floor chamber is lit by small off-center windows, and is flanked by a straight mural stone stairs for 11 steps to the first floor. The stairs become spiral from the 2nd to the 4th floor level. In all the stairwell contains 54 steps. Although the ground floors of most contemporary towers were usually completely dark, Carrigaphooca's ground floor contains three windows, which are deeply recessed giving an appreciation of unusual thickness of the walls. The narrow windows are accessible to birds, particularly crows, who since the towers ruin, have dropped layers of twigs. The building is a relatively simple design. There is one surviving window, located on eastern front and opposite the entrance to the 2nd floor, and which like the remains of the other windows, contains a fairly basic
linteled block head. Carrigaphooca does not contain a fireplace, suggesting, according to a report by the Heritage Unit of
Cork County Council, that it was "built more with protection in mind rather than comfort". According to the writer Barry O'Brien, Carrigaphooca was "in its day...quite a splendid building and must have offered considerable security to the besieged and a formidable challenge to the besiegers. The top floor may have also contained living quarters, and perhaps a fireplace. The windows on the northern and southern walls are significantly larger than on the other floors and give a panoramic view of the surrounding valley, as well as the distant the
Killarney Paps and
Mullaghanish. The tower once contained two defensive outer walls, which are now lost and have left no traceable remains. It contains the remains of two corner
bartizans on two opposite wall tops. They appear as projecting stone boxes with gaps that were used as protection by defenders when shooting downwards at attackers. The first floor consists of a single room which was probably used as quarters for the guards. The timbers bearing the floor were supported on still visible limestone carved
corbels. During the 1970s, the Office of Public Works undertook restoration of the site, and added a flight of steps leading over the rock base, joining with the main entrance. The restoration included the addition of narrow stepped
turret to give access to the unguarded walk-way around the roof, although it was later blocked by a gate in the mid 1980s for safety reasons. ==References==
