Garryowen Irish: Garraí Eoin is a neighbourhood in Limerick, Ireland. The word Garryowen is a transliteration of the Irish Garraí Eoin - "the garden of John" - and relates to the association in the 12th century between St John's Church and the Knights Templar whose house in Limerick was dedicated to St John the Baptist. In medieval times Garryowen was located just outside the Irishtown area of the walled city of Limerick. The citadel (located in the grounds of St John's Hospital) was the Irishtown's main fortification. In 1690, it was the scene of a heroic Jacobite defence-the battle of the breach-which was fought nearby. The sally port of the original stronghold has been incorporated into the structure of St John's hospital. Other parts of the city walls can still be seen within the hospital grounds.
