a bishop's see in the county of Clare and province of Munster, in Ireland, 86 miles from Dublin, otherwise Lounia. It was anciently written Kill-da-Lua, i.e. "the church of Lua," from Lua or Molua, who about the beginning of the 6th century founded an abbey near this place. St Molua appears to have derived his name from Lounia, the place of his residence, as was customary amongst the ancient Irish. On the death of St Molua, St Flannan his disciple, and son of the chief of the district, was consecrated bishop of this place at Rome about the year 639, and the church endowed with considerable estates by his father Theodoric. Towards the close of the 12th century, the ancient see of Roscrea was united to that of Killaloe; from which period these united bishoprics have been governed by the same bishops. At Killaloe is a bridge over the Shannon of 17 arches; and here is a considerable salmon and eel fishery. There are many ancient buildings in and about this town. The cathedral is a Gothic edifice in form of a cross, with the steeple in the centre, supported by four arches; it was built by Donald king of Limerick in 1160. There is a building near it, once the oratory of St Molua; and there is another of the same kind in an island of the Shannon, having marks of still higher antiquity. The see house of the bishop is at Clarisford, near to Killaloe. Adjoining to the cathedral are yet some remains of the mausoleum of Brien Boru.
