A British property company has agreed to the erection of a plaque in honour of Violet Gibson who tried to assassinate Italian Fascist leader Benito Mussolini.
The real estate company Westhill said it will work with Dublin City Council to facilitate the installation at 12 Merrion Square, which was Ms Gibson's childhood home.
Ms Gibson, who came from a privileged Anglo-Irish background, attempted to shoot the Italian leader in 1926.
Mussolini was reported to have moved his head at the last minute and the first shot grazed his nose while the second misfired.
Police had to save Ms Gibson from being killed by the crowd and she was deported to England, an act for which the British government is said to have thanked Mussolini.
However, then aged 50, she was detained in a psychiatric hospital for the rest of her life despite repeated pleas for her release.
Councillor Flynn's motion read: "It is now time to bring Violet Gibson into the public eye's and give her a rightful place in the history of Irish women and in the history of the Irish nation and its people".
She died in 1956 and is buried in England.
