“The Banshees of Inisherin” was filmed mainly on two real Irish islands: Inishmore (Inis Mór) in County Galway and Achill Island in County Mayo on Ireland’s west coast.

Main answer (Quick Scoop)

  • The fictional island of Inisherin does not exist in real life; it’s a blend of locations on Inishmore and Achill Island.
  • Principal photography started on Inishmore (one of the Aran Islands), then moved to Achill Island later in the shoot.
  • Inishmore provided many of the sweeping cliff and village landscapes, including the area of Gort na gCapall and views of the ancient fort Dún Aonghasa.
  • Achill Island was used for key spots like Keem Bay (Colm’s clifftop cottage and the beach in the final scenes), Purteen Harbour, Corrymore Lake, and the custom-built J.J. Devine’s pub at Cloughmore.

So if you’re wondering “where was Banshees of Inisherin filmed,” the on-screen Inisherin is really a cinematic mash‑up of Inishmore and Achill Island along Ireland’s Wild Atlantic Way.
