Frequently Asked Questions


Early History


The Cahir Castle was constructed around 1142 by Connor O’Brien. It was established in two stages. The side by the street in the present day was erected 200 years earlier than the side where an audio-visual show about its history takes place today. 

Cahir Castle had state-of-the-art defensive architecture, a lot of which remains intact to this day. The castle belonged to Phillipp of Worcester, who owned the land during the early 13th century after being granted it by King John. His nephew, William Worcester succeeded him afterward. Later the Worcesterter’s wedded into the DeBermingham family, who took over the castle until the late 14th century.

Medieval Period

In 1375, the castle was given to James Butler – the first Duke of Ormond – as a token of appreciation for his faithfulness towards Edward III. It was inherited by his son James, who passed it on to his offspring.

Under the Butlers (16th-17th Century)

Thomas Butler was made Baron of Cahir by Henry VIII in 1543 as a gesture of appreciation for his loyalty to the crown. In the 16th-century, the castle was besieged by the Earl of Essex upon the orders of Queen Elizabeth I. The siege lasted three days, and such events continued to occur frequently throughout this period until the Butler family regained its hold over the territories. 

Eventually, their authority declined, and the castle was surrendered to Inchiquin in 1647. It was retaken in 1650 by Cromwell II, after which the lands were bestowed to Lord Cahir, who was then a child.
