RIVERSIDE, is located in the village of Clarecastle, just south of Ennis, in County Clare, Ireland on the outskirts of the main town. The main Limerick-Ennis-Galway N18 road passes through Clarecastle, and the length from Ennis to Clarecastle is built up, such that Clarecastle has the appearance of a suburb of Ennis.

Clarecastle takes its name from CLAR ADAR DA CHORADH or CLAR-ATHA-DA-CHORADH, meaning the bridge between two weirs, which almost describes the castle's function, situated as it is on an island of the Fergus River at its narrowest navigable point.

The word CLAR, meaning board, is generally used to signify a wooden bridge and the earliest settlement here may simply have been referred to, in Irish, as "the wooden bridges". A second explanation of the name stems from the de Clare family having been given land in Kilkenny and Thomond, including Bunratty and Clarecastle.

The town of CLARE, so called after the castle, was of such importance that it gave its name to the county in 1579.
Until recent times it was simply known as Clare or Clare Castle.
