NEWCASTLE, a borough town of Ireland, in the county of Dublin, and province of Leinster, which returns two members to parliament, and holds two fairs, 9th of May and 8th of October.

NEWCASTLE is also the name of a handsome town

Newcastle in the county of Limerick and province of Munster, on the high road to Kerry, 114 miles from Dublin. Here was a religious house possessed by the knights templars. It is said, they used some barbarous customs which greatly disgusted the Irish, who, watching a favourable opportunity, attacked a number of the knights riding out together and put them to death; the place is still remembered where their remains were interred. This order was suppressed in the famous council of Vienna, 22d of March 1312. Newcastle consists of a large square where markets and fairs are held; on the northern side stands a market house, with an assembly room; on the south side is the church, which is the neatest in the county; it was finished in 1777 at the sole expence of Lord Courtenay. It stands close to the walls and fortifications of the knights templars, of which one of the castles is fitted up for Lord Courtenay's agent.
