Seemingly there are some 100 places around the world called Newcastle, six of them located in Ireland (one of these, in County Meath, is a couple of miles away from the more substantial settlement of Oldcastle). Newcastle, County Tipperary is one of the smaller holders of the name, being a small village seemingly of little note. But it contains two substantial mediaeval ruins, one being a large 12th/13th century church and the other the castle from which Newcastle takes its name.
The ‘new’ castle in County Tipperary presumably replaced an older one, but there does not appear to be any information about the latter. What remains can be seen close to the banks of the river Suir, the navigable possibilities of which was one reason for the choice of this site. The castle is believed to have been built for the Prendergast family, the first of whom Maurice de Prendergast, was among the Cambro-Norman knights who accompanied Richard de Clare (otherwise known as Strongbow) to Ireland and then settled here. Around 1230 his grandson, William de Prendergast exchanged lands he had inherited in what is now County Limerick with Jeffrey de Marisco for those in this part of Tipperary. There may already have been some kind of castle already erected but the ruins seen today were certainly enhanced and enlarged by the Prendergasts who remained in occupation until the mid-17th century. In the aftermath of the Confederate Wars, Edmond Prendergast’s estates were taken from him by the Cromwellian government and the link with Newcastle broken. Edmond Prendergast’s grandson, Sir Thomas Prendergast, who grew up in poverty, led an extraordinarily adventurous life. Having fought in the service of James II, he allied himself to William III after the Treaty of Limerick. A Roman Catholic, he was involved in a Jacobite plot to kill the king, but then switched sides and provided evidence that helped to convict many of his former fellow-plotters. He then seems to have conformed to the Established Church and was rewarded with lands around Gort, County Galway that provided an annual income of £500. Created a baronet in 1699, he acted as MP for Monaghan borough, 1703-09 while also serving in the army, rising to the rank of brigadier-general in February 1709. However, the following September he was killed at the Battle of Malplaquet.
The castle at Newcastle consists of a number of buildings enclosed within what remains of a bawn wall; among the more notable extant structures is a large vaulted hall and a circular tower, both relatively intact although much of the rest of the property is in poor condition. Quite when the castle was abandoned is unclear. One suggestion is that it was badly damaged in the late 1640s/early 1650s at a time when the Prendergasts were displaced. But the ruin of so many buildings in Ireland is attributed to Cromwellian forces that it is hard to know whether or not such was the case in this instance. Whatever the truth, the lands on which it stands were eventually granted to the Perry family, whose main residence from the early 18th century onwards was some ten miles north at Woodrooff, County Tipperary. In 1837 Samuel Lewis wrote that the old castle ‘forms a very picturesque feature in the landscape.’ Such remains the case today.
