These lands were later handed back to (or taken back by) King Henry III and granted to Thomas De Clare, a descendant of Strongbow in 1276. De Clare built the first stone structure on the site (the second castle). This castle was occupied from ca. 1278 to 1318 and consisted of a large single stone tower with lime white walls. It stood close to the river, on or near the site of the present Bunratty Castle. In the late 13th century, Bunratty had about 1,000 inhabitants. The castle was attacked several times by the O'Briens (or O'Brians) and their allies. In 1284, while De Clare was away in England, the site was captured and destroyed. On his return, in 1287, De Clare had the site rebuilt and a long fosse built around it. The castle was again attacked but it did not fall until 1318. In that year a major battle was fought at Dysert O'Dea as part of the Irish Bruce Wars, in which both Thomas De Clare and his son Richard were killed. Lady De Clare, on learning this, fled from Bunratty to Limerick after burning castle and town. The De Clare family never returned to the area and the remains of the castle eventually collapsed. As the stones were likely used for other local construction works, no traces remain of this second castle.
