Dunkerron Castle

The four-storey tower house was built in the 13th century on a limestone outcrop as a Norman (Carew) stronghold. An inscribed plaque, dated 1596, recorded the castle's association with the O'Sullivan Mór and MacCarthy Reagh dynasties. The castle was the family seat of the O'Sullivan Mór for some time. The main O'Sullivan Mór familial seat moved to nearby Cappanacush Castle during the 17th century, and antiquary Samuel Lewis noted that both castles were "traditionally said to have been defended" by their O'Sullivan Mór owners during the mid-17th century Cromwellian conquest of Ireland. The O'Sullivan castles and lands at Dunkerron and Cappanacush were confiscated following this conflict under the Act for the Settlement of Ireland 1652, and assigned to Cromwellian supporter William Petty. By the 19th century, maps record the castle and court as being "in ruins", and a Victorian manor house, Dunkerron House, was built on the estate around that time. Dunkerron Castle gives its name to the barony of Dunkerron, later divided into Dunkerron South (the southern part of the Iveragh Peninsula) and Dunkerron North (the area around MacGillycuddy's Reeks). ==Title==

One of the last members of a branch of the O'Sullivans was Donal O'Sullivan, who died on 16 April 1754, without issue or heirs. The title he bore, the "Prince of Dunkerron", became extinct on his death. The British monarchy did issue a peerage title of Baron Dunkeron to John Petty. (John Petty was Sheriff of Kerry from 1732, and a descendant of the William Petty to whom the lands had been given following the Cromwellian confiscations). The title assigned to Petty was not however related to the original title of the native Irish nobility. ==References==
