Modwenna was a 7th-century Irish noblewoman who became a nun and an abbess in England. She is primarily recognized for establishing Burton Abbey on an island within the River Trent in Staffordshire. While medieval accounts suggest she later traveled to Scotland and died in Langfortin near Dundee, her remains were reportedly brought back to Burton upon Trent for interment. Some historians suggest her identity may have been conflated with other figures, such as the Irish saint Monenna or a different Scottish holy woman.
