Cathair Pheatar is a cave in the townland of Ballymagibbon. There is an entrance into it like a doorway with a few steps down. About thirty years ago boys used to go down into it with a lighted candle, they were afraid to go down far for fear the candle would quench. It has a wall on each side about six feet high. The tunnel is leading to Moytura House. In the year 1865 there was noise heard there laying a table with forks and knives. Lights were seen at the mouth of it by local people.
