events and island mythology: Dún Bhaloir (“Balor's Fort”) is located on the island's eastern side, on a peninsula surrounded on three sides by cliffs. The fort is accessible only by crossing a narrow isthmus that is defended by four earthen embankments. An Eochair Mhór (the “Big Key”) is a long, steep-sided spur jutting from the east side of the peninsula and ending in a crag called An Tor Mór (the “Big Rock” or the “Big Tower”). The spur has prominent rocky pinnacles known as “Balor's soldiers” (Saighdiúirí Bhaloir). They give the spur a 'toothed' appearance, helping to inspire the name “the Big Key”. The Wishing Stone is a precipitous, flat-topped rock alongside the northern cliff-face of Balor's Fort. Traditionally, a wish is granted to anyone foolhardy enough to step onto the rock, and also to anyone who succeeds in throwing three stones onto it. An Cloigtheach (the “Bell Tower”) is the largest structure to have survived the 16th-century destruction of the monastery (see history section above). The round tower was built in the 6th or 7th century. The Tau Cross (a T-shaped cross) is believed to date from the 12th century. It is one of only two Tau crosses in Ireland (the other is in Kilnaboy, County Clare). Móirsheisear (“Grave of the Seven”): Móirsheisear (which literally means “big six”, but is nevertheless a term signifying seven) is the tomb of seven people, six men and one woman, who drowned when their boat capsized off Scoilt an Mhóirsheisear (the “Cleft of the Seven”) on the island's northwest coast. According to local superstition, clay from the woman's grave has the power to ward off vermin. The Lighthouse, standing at the west end of the island, was built between 1828 and 1832 based on a design by George Halpin, a noted designer of Irish lighthouses. In April 1990, the lighthouse was automated. It is one of three lighthouses in Ireland into which a reference station for the Differential Global Positioning System (DGPS) has been installed. The lighthouse is at coordinates The Torpedo: A torpedo can be seen midway between An Baile Thiar and An Baile Thoir. It washed ashore during World War II and was then defused and moved to its present location. Flora and fauna The island is a designated “Important Bird Area”. It is a breeding site for corn crakes (Crex crex), a globally threatened species whose numbers have fallen as
