The closing bastion towards Queen Elizabeth I inside the First Desmond Rebellion, Listowel Castle turned into constructed in the fifteenth century and was the closing castle of the Geraldines to be subdued. It fell after 28 days siege to Sir Charles Wilmot on five November 1600, who had the fort's garrison finished in the following days. One of the satisfactory examples of Anglo-Norman structure in County Kerry the citadel has now been restored to a number of its former glory. The fortress is open to the general public for excursions on a each day foundation. The fort became the assets of the Hare circle of relatives, the holders of the name of Earl of Listowel, after reverting far from the Fitzmaurices, Knights of Kerry. It is now a national monument.
Today, the remnants of the fortress include two of its four towers, which might be joined by way of a heavy curtain wall, and the uncommon function of an arch below the battlements. Archaeological excavations and facts of the fort display that it became firstly of similar shape to Bunratty Castle, Co. Clare. In 2005, recuperation works had been started by way of the Board of Public Works. The stonework has been wiped clean with the aid of a team of expert craftsmen, whilst the higher section, which had become particularly distressed with the passing of time, has been restored and rendered water-proof.
