Monastery The monastery is built into a terraced shelf above sea level. It contains two oratories, a cemetery, crosses, cross-slabs, six
clochán-type domed
beehive cells (of which one has fallen) and a medieval church. The cells and oratories are all of dry-built
corbel construction, whereas the church, which was constructed at a later date, is of mortared stone.
Cells huts with
corbel roofs The largest hut is known as cell A and has a floor area of 14.5 × 3.8 metres and is 5 metres high. Like the other huts, its internal walls are straight before narrowing to accommodate its dome roof. The protruding stones in the interior act as pegs and are placed at about 2.5 metres to support the roof, and in some instances may have supported upstairs living quarters. The protruding stones on the exterior most likely were anchors for
thatch roofing. Some cells contain recesses that may have been formed to contain cupboards. The main oratory is boat-shaped and measures 3.6 × 4.3 metres. It has an altar, a small window on its eastern wall. The small oratory is situated on its own terrace, at a relative distance from the main complex. It measures 2.4 × 1.8 × 2.4 metres and contains a low door (0.9 × 0.5 metres) and a comparatively large, one-metre-high window on its north-eastern wall.
St Michael's Church St. Michael's Church dates to the 10th or early 11th century. It was originally constructed from mostly lime mortar with imported
sandstone from
Valentia Island. It is today mostly collapsed, with only its eastern window still standing. The centre of the church contains a modern gravestone, dated 1871, erected for members of the family of one of the lighthouse keepers.
Monk's Graveyard The Monk's Graveyard is partially collapsed and smaller than when it was in active use. It contains stone crosses with mostly plain inscribed decorative patterns on its west side, two of which are highly detailed and believed to be early features of the site; in total over a hundred individual stone crosses have been found on the island. There are several large
orthostats on its north and west sides. There are two dry stone
leachta on the site. The larger is positioned between Saint Michael's Church and the main Oratory, and is thought to pre-date both, and once had a large upright cross at its western end, which is now broken off. The other is located against the monastery retaining wall at the south of the oratory. Human remains have been found underneath both.
Oratory The
oratory is two hundred metres above sea level and fifteen metres below the summit, is the largest and is in good condition. The main oratory is still largely intact and contains its original
altar, bench, a water cistern and what is likely the remnants of a
shrine. The masonry work is typical of the
Early Christian period in Ireland. The interior of the main building is long and wide. The enclosure wall is made from mostly small stones. Although it is now worn and mostly knocked down, it would once have been around high. Today the interior is full of stone rubble fallen from the structure and the fragments of a tall
stone cross. The leacht outside of it was probably used as a shrine or altar; it is too small to have been a burial site.
Hermitage The hermitage is located on the opposite side of the island to the monastery. It was built below the south peak and is significantly more difficult and hazardous to approach. Today access is restricted and permitted only after prior arrangement. The south peak is approached from Christ's Saddle via a very narrow and steep series of
rock-cut steps. Exposed and unprotected, the steps are vulnerable to fierce winds that at times approach hurricane force. The pathway passes through the Needle's Eye, a rock chimney formed by a narrow vertical crack in the peak. Though the hermitage's origins and history are not as well studied as that of the monastery, it seems likely that it was built later; given the presumed difficulty of its construction which would have involved the movement of large pieces of stone. These would have had to be carried up almost sheer cliff faces, and thus the builders would have needed to have had the monastery as a base. The eroding effect of frost on the island's major fault line provided the masons with large amounts of materials for the construction. The hermitage consists of several enclosures and platforms situated on three main
terraces cut into the rock. These are today known as the Oratory, Garden and Outer Terraces.
Outer terrace The outer terrace is situated on three stepped ledges some distance from the main complex and is difficult to access. Its only masonry consists of a wall along its steep and exposed perimeter. Wondering why such an inaccessible and harsh outpost might have been built, the historian Walter Horn wrote that "the goal of an ascetic was not comfort" and recalled that the
Cambrai Homily states: "This is our denial of ourselves, if we do not indulge our desires and if we abjure our sins. This is our taking-up of our cross upon us if we receive loss and martyrdom and suffering for Christ's sake."
Stairs and paths Each of the three landing areas lead to long flights of steps (known as the east, south and north steps) built by the first generations of monks to inhabit the island. They may have at one time formed part of a larger network; traces of other, possibly earlier steps have been uncovered elsewhere on the island. Archaeological evidence shows that basal sections of each series of steps were rock-cut, giving way to more stable
dry stone masonry once they reached an altitude where the sea waves would no longer
weather them. Later the base steps were replaced with dry-stone paths. The north steps lead from Blue Cove and consist of two long and steep continuous flights known as the upper and lower steps. The upper pathway was built from dry stone but is in very poor condition in places; given the steep face on which they are built, they are prone to erosion and the impact of falling stone from the cliffs directly above. The lower rock-cut portion has been heavily weathered by the sea, and some of the ground around them has collapsed; the portions where steps are lost have been replaced with
ramps. A
parapet at their lowest base was added in the 1820s, and they were widened during the construction of the lighthouse. The south steps are most commonly used today and merge with the north steps at Christ's Saddle, to lead to the monastery. They cross several archaeological features, including a prayer station and walling. They are in good condition and were probably repaired by the lighthouse builders. Their weakest point, directly above Christ's Saddle, suffers wear and tear from continual use by modern visitors and requires continual maintenance. The landing steps may have been built by the lighthouse builders; 14 steps apart from the main landing are virtually inaccessible, stopping short at both ends and leading neither to the sea nor to the highest levels. The lower part of the east steps above Blind Man's Cove was heavily blasted with dynamite in 1820 during the construction of the pier and Lighthouse Road, and are now inaccessible from the landing point. The steps above this level, on a very steep climb along a sheer face, have been subject to conservation, most recently in 2002/2003 when large amounts of overgrowth were removed, and are today in good condition. ==In culture==
