Irish annals tell us that the first religious establishment in Cong was founded by St Fechin in the year 624; but John O'Donovan says in a note in his translation of the Four Masters that Roderick O'Connor founded and endowed the Abbey of Cong. That a religious house of some kind was founded in it by St Fechin there can be no doubt at all, for up to a recent period it was known as Cunga Fechin, or Cong of Fechin. O'Donovan may have meant that Roderick O'Connor endowed and founded the abbey, the remains of which exist at present, for not a vestige of the original building founded by St Fechin remains. It was, like most of the very early churches and religious houses of ancient Ireland, built entirely of wood, and has consequently long ago disappeared. Cong was originally a bishopric. There were five bishoprics in the province of Connacht--namely, Tuam, Killala, Clonfert, Ardcharne, and Cong. The Synod that settled the question of the bishoprics of Connacht met at Rathbrassil, in what is now the Queen's County, in 1010. The abbey, the remains of which still exist, was founded in 1128 by the Augustinians, during the reign of Roderick O'Connor's heroic father, Turloch. Roderick subsequently endowed it, and ended his days in it. It is an interesting and suggestive fact that most of the great religious establishments of Ireland were not only founded but built in the material that now remains of them before the Anglo-French invasion, showing clearly that that event put a stop to almost everything that could be called progress. The invaders, although professing the same faith as the invaded, were much more anxious to build castles than churches. There was hardly a castle in Ireland before the time of Strongbow. This was not caused by ignorance of the art of building among the Irish, for some of the round towers and churches erected long before the time of Strongbow are as perfect specimens of architecture as were erected in any country at the same period. The native Irish king, or chief, was contented with a wooden house surrounded by an embankment, capped with a palisade of wood; but the Norman raised mighty edifices of stone to protect him from the wrath of those he had robbed.
