It is situated near Lough Bunny, off the R460 road from Corofin to Gort, at the northeastern edge of the Burren National Park, and close to the border with County Galway.

[2] The official Irish-language name recorded in the Placenames Database of Ireland is Boston.

[3] Local signposts erected by Clare County Council use the Irish name Móinín na gCloigeann "little bog of the skulls",[2] which appears to be a mistaken transfer from a different place: a townland called "Moneennagliggin North" or "Boston" in English, near Cratloe in the south of the county.

Today, the ruins of the castle are a reminder of the past sieges endured by its previous occupants.

In 1846 Boston was described as the "principal hamlet" of Kilkeedy,[6] although Tubber, County Clare now spills over into the far end of the parish.
