There are the remains of only three churches extant in Clonmacnois; but we know from authentic annals and history that there were nearly a dozen churches in it at one time. What became of them, or where they stood, cannot now be known. Many of them were, probably, wooden churches, and, when once destroyed, left no trace. The ruins of the ancient nunnery are distant nearly quarter of a mile from the churchyard, on the grounds of a gentleman named Charlton. It is only about thirty years ago since an attempt was made to clear away the rubbish in which they were buried, and to try if any of the sculptured stones could be recovered. The excavations were made under the supervision of the Protestant Bishop of Limerick. Sculptured stone-work of the highest order of art was dug up from many feet under the surface where the destroyers had buried it. Visitors to Clonmacnois will not have any difficulty in seeing the ruins of the nunnery, for Mr Charlton willingly permits visitors to see them. It is not only curious, but hopeful and pleasant, to find people of the same religious belief altering so much for the better as time rolls by. Whilom Protestant men and a whilom Protestant Government did all they could in the seventeenth century to turn Clonmacnois into a heap of ruins, almost as void and as shapeless as those of Babylon; but Protestant men and a Protestant Government in the nineteenth century have done everything in their power to save it from further decay, and to dig up its sculptured stones from the dust in which ancient Protestant fanaticism and bigotry had buried them. Clonmacnois was founded by St Kieran, who died in the year 549. There are records of the erection of most of its ancient buildings to be found in Irish annals and history. According to the _Chronicon Scottorum_, a work of high authority, the Cathedral was built in the year 909. The Cathedral that existed when Turgesius the Dane obtained sway for some years over the greater part of Ireland, and when his wife used to issue her orders from that building, was probably of wood, for no trace of it appears extant. Doctor Petrie says that the larger round tower was erected in the tenth century, and the smaller one in the eleventh or early part of the twelfth. There is good authority to prove that the nunnery was erected and endowed by the too well-remembered Dearvorgil, wife of O'Ruairc, whose _liaison_ with Dermot Mac Murrough, King of Leinster, is popularly believed to have brought about the Anglo-Norman invasion of Ireland.
