Gleann Eidhneach means the valley of ivy. However, it is possible that the correct Irish name is actually Cluain Eidhneach or "ivied retreat". The name predates the castle. Parishes were often named after the principal church and this may be the case here.
Location

Antiquities
Castle
The 16th-century Gleninagh Castle, an L-shaped tower house, stands on a hillside looking out over Galway Bay. It was an O'Loghlen stronghold from the early 16th century. Although it changed hands many times over the next centuries it was eventually regained by the family who used it until c. 1840. In 1839, it was described as "in good repair". A visitor in 1843 said the castle was being used as a barn by Mr. Blood, its proprietor. The upper part of the building was used as a dove-cot and abounded in pigeons. The tower measures by. In 1839 it was thatched with straw. There are four stories. The single square turret contains a spiral stairway. The entrance doorway on the first floor of the turret is protected by a machicolation high above. There are round bartizans in three of the main tower's corners. A number of window openings in the end wall were later closed so they could be used for fireplaces.
Church
The medieval church is of indeterminate age, but was in existence by 1302. There are some indications that the site may have been an earlier monastic settlement, such as a curved field wall shown on the 1842 OS map which could have been a remainder of a typical monastic enclosure wall. Domestic waste was discovered near the church and there are other signs of habitation such as outbuildings. Absent excavation, however, the age of the ecclesiastical site remains uncertain. The church was described in 1839 as being mantled in thick ivy. The floor measured. The walls were thick and about high. The south wall had a pointed doorway of cut stone that was high, measured to the vertex of the arch, and wide. The south wall had two windows, one quadrangular and the other round-topped, both fairly recent. There was a window in the east gable about high and wide. In the outside the window opening was. As of 1897, the church was in a good state of preservation. Today, though in poor repair, it is accessible to the public by a footpath from the road. The church is small for a parish church, which probably reflects the small population and poverty of the area which may well have been the poorest parish of the diocese of Kilfenora.
Gleninagh Lodge
The partially overgrown remains of this structure lie at the end of the lane connecting the road to the tower house. Mid-19th century maps show a substantial assembly of large buildings. The estate included a large formal garden south of the holy well. At the time, most of the land in this area was owned by the lodge's proprietor, William Bindon Blood, a descendant of Colonel Thomas Blood, who tried to steal the English Crown Jewels in 1671.
Others
Near the castle is a holy well dedicated to the Holy Cross, which has many recorded names. The well has a little stone vault over it, with a Gothic-type arch and a cross on top. It was thought that performing stations at the well would help with problems with the eyes. In the early 1840s the votive offerings were reported to include human skulls. At least until that period the well was a destination for pilgrims. Another well called Tobar Cornain is in the townland of Gleninagh North. This is today covered by a Gothic Revivalwell house and lies right next to the road. There is a large heap of stones called Dough Branneen in the townland of Aughaglinny. There is a stone ringfort called Caher doon Fergus in the townland of Murroogh with caves underneath it, said to be haunted. East of the castle is a lime kiln, previously thought to be a Fulacht Fiadh.
History
In 1544 King Henry VIII of England granted Gleninagh to Richard Harding. The castle was owned by James Lynch of Galway in 1570. The lands of Gleninagh were owned by the see of Kilfenora in 1629. In 1837 a parish was in the Catholic union or district of Glyn, or Glenarraha. The population in 1841 was 886 in 146 houses. In 1845 the main settlements were the villages of Glaninagh, Murroghkelly and Murroghwohy.
