A monastery is said to have been founded on Low Island by
Saint Senan of Iniscattery, before
Saint Patrick came into
Munster. Saint Moronoc is said to have had a cell here at the time of Senan's death, called "the Penitentiary of Inisluaidhe". There were many Danish forts and tumuli in the parish. The Moland Report of 1703 said of "Kildizert" that it "has on it ye ruins of an old church and several cabins." The ruins of the old church still remained in the burial-ground near the shore as of 1837. In 1831, the population was 4,501, and in 1841 it was 5,130 in 753 houses. In 1834, there were 4,802 Catholics and 32 Protestants. In 1837, the village contained about 60 houses, irregularly built. A steamboat passed daily on the way to or from Limerick. An application had also been made to the Board of Public Works to improve the Quay near Kildysart, from which pigs, corn, butter and agricultural produce were sent to Limerick in boats; and building material, groceries and other essentials were brought back in return. ==Today==
