In 1114 Iona was seized by the King of Norway, who held it for fifty years before Somerled recaptured it, and invited renewed Irish involvement in 1164: this led to the construction of the central part of the cathedral. Ranald, Somerled's son, now the 'Lord of the Isles', in 1203 invited the Benedictine order to establish a new monastery, and an Augustinian Nunnery, on the Columban Monastery's foundations. Building work began on the new abbey church, on the site of Columba's original church. The following year, in 1204, the site was raided by a force led by two Irish bishops. This was a response by Ireland's Columban clergy to the loss of its connections and influence at this significant site founded by St Columba.
