Seán O'Casey set all three of his "Dublin Trilogy" (The Shadow of a Gunman, Juno and the Paycock and The Plough and the Stars) in tenement houses in Georgian Dublin. In particular, The Shadow of a Gunman opens in A return-room in a tenement house in Hilljoy Square which is raided by the Auxiliaries during the play. This room is thought to have been based on O'Casey's former tenement home. Although the original house was demolished in the 1960s, it was later replaced by a building with a Georgian façade that now stands on the site. O'Casey subsequently lived in another Georgian house very close to Mountjoy Square at 422 North Circular Road; in that house which still stands today, is where he wrote the trilogy, before later moving to London during the nineteen twenties.
