The medieval town of Rindoon was developed around a castle built by Toirdelbach Ó Conchobhair and Geoffrey Marisco in 1227. Rindoon had very little defence and so was attacked in 1236 by Phelim Ó Conchobhair. Seeing how vulnerable they were, the residents applied to King Henry III for a town wall. Only one known murage document from 1251 speaks of the King sending money to enclose and protect the towns and castles of both Athlone and Rindoon.
