a post and fair town of Ireland pleasantly situated in the county of Kildare and province of Leinster, about 8 miles from Dublin. Near it are the ruins of the church and castle of Cony. The castle of Leixlip is beautifully seated on the banks of the river Liffey; it is a fine edifice with large and pleasant gardens, at one side of which is a fine waterfall called the Salmon-leap, there being plenty of that species of fish hereabouts. A mile from this is Castletown, the magnificent seat of Mr Conolly. There are three fairs here in the year.
