The "Book of Armagh," written in the year 802, and now in the library of Trinity College, Dublin, duly relates that, after proceeding for two miles down the road slowly, the oxen turned from the main thoroughfare and rested at Dundalethglass, the site of the present Cathedral of Down. The monks from Armagh submitted to the will of heaven, and there the sacred dust was laid. Shortly after this, about 495, a church was built upon the site now occupied by the present edifice. It was rebuilt in the twelfth century, a considerable portion of the original walls being retained and several interior arches. And those walls and arches remain to-day. It is therefore the oldest structure in Ireland and is entitled to the veneration it receives. It stands in a grove upon the summit of a hill, a plain, dignified pile of perfect proportions, with a square tower and four spires--in no way imposing, but beautiful in its simplicity. [Illustration: DOWN CATHEDRAL, DOWNPATRICK, WHERE ST. PATRICK LIVED, AND IN THE CHURCHYARD OF WHICH HE WAS BURIED] The interior of the church is said to be precisely as it was originally built, there having been no change in the arrangement. And most of the columns which sustain the arches and several of the arches were a part of the original building. The "Annals of Ulster" give the names of the abbots who had charge of the monastery that was built in connection with the church, as far back as the year 583, although there are several wide gaps in the records of the eighth, ninth, and thirteenth centuries. The abbey was plundered and partially destroyed on no less than eight occasions, between the years 824 and 1111, and the "Annals of Ulster" give the particulars of each invasion. In 1177 Sir John de Courcy, the most powerful and able lieutenant of Strongbow, who assumed authority over the kingdom of Ulster, made Downpatrick his principal residence and erected there a strong castle, the greater portion of which remained until about half a century ago. At his time the church and the monastery were occupied by Augustinian monks, who were driven out by De Courcy and replaced by Benedictines from the Abbey of Chester, England, and the church was rededicated in honor of St. Patrick, having previously borne the name of the Holy Trinity. And De Courcy gave the abbey a liberal endowment. He also erected a Celtic cross, which is believed to be the same that was recently recovered in fragments, carefully mended and placed in the churchyard. Among the endowments of the Downpatrick abbey were four of the principal ferries across the rivers of Ulster, forty-seven "town lands," which probably correspond to our townships, and every tenth animal upon the farms of Ulster. Of the extensive monastic building erected by De Courcy's generosity not a trace remains except the foundations, and these are covered with the accumulated débris of four centuries.
