Tomfinlough (Irish: Tuaim Fhionnlocha)[1] is a civil parish in County Clare, Ireland.

The parish lands were often raided by Irish, Viking, Norman and English forces in the years that followed.

The ruined parish church stands at the northern end of the lake named Finn Lough or Fenloe.

[2] It is in the barony of Bunratty Lower[a] in County Clare, about 2 miles (3.2 km) northwest of the village of Six-Mile-Bridge.

[8] In 1854 a hoard of buried treasure hidden in a small stone chamber was unearthed in the Mooghaun North townland during the construction of the Limerick and Ennis Railway.

In 1744 the High Sheriff for Clare, John Westropp, reported to the authorities that, "I have according to your instructions made strict search in Ennis and in several other places where we had the least suspicion of priests and had the army from Clarecastle to assist me - but could find none.

[12] Large blocks of limestone in the southwest of the site are traces of a pre-Norman building which could date to the 10th century.

Around 1300 the de Clare family restored the church and added at least two sandstone windows to the south and east walls.

It had large cut stones at its ends, like the angles of a house gable, and a doorway in the center 4.75 feet (1.45 m) high measured from ground level as it then was.

[13] A traditional story tells of Luchtigern curing a woman inflicted by the plague, who came to him when he was working in the field at Tomfinlough with two deacons.

[15] There is a stone in the Tomfinlough graveyard wall with two raised solid circles on its face, about six inches in diameter.
