Inishere ( Inis Óirr in Irish, meaning "the south island") is the smallest of the three islands with a population of only about 300 people. Despite its size you can still find pubs, B&Bs, a hotel and a campsite and there is plenty to do and see. Inis Óirr is geologically similar to the Burren in County Clare, comprising mostly of rock. Like the Burren, many rare and exotic flowers and plants grow there. Ancient monuments worth seeing include ruins of Saint Kevin's Church, or Teampall Chaomhain, now sunk deeply into a sandy hill close to the shore. Not far from the small village is O'Brien's Castle, a 15th century tower house that stands within a stone fort. Also worth visiting are St. Gobnait's Church, or Cill Ghobnait, the Church of the Seven Daughters, or Cill na Seacht nInghean.
