(Bermond's isle) A former Benedictine abbey in Southwark, London. It was founded, 1082, by Alwyn Childe, a citizen of London, who established there a community of monks subject to Cluny; it became an abbey, 1399. A hospital and relief house of Saint Thomas in Southwark, founded by the prior, 1213, was attached to the monastery for over 200 years. The abbey was suppressed by Henry VIII, being at that time the only Cluniac abbey in England.
