In the line of walls is a large window which once occupied the gable end of what is likely to have been the great hall. The mullions of this window, which remained intact until recently, were remarkable for being of red sandstone, which is unknown in the country. The situation of the chapel may still be discerned by the remnants of some of the stone carving which once adorned its sacred walls. In 1192 Archbishop Comyn obtained a patent authorising him to hold an annual fair in his manor of Swords, and in 1387 this privilege was confirmed to Robert de Wikeford. King Henry III. enlarged the possessions and added new privileges to the manor, which he granted to Henry de Loundres in 1216, on condition that he should build and maintain Castlekevin, near Glendalough, County Wicklow, to defend the pale in that quarter from the invasions of the great Irish families of O’Toole and O’Byrne. We read later (1380) that Sir Nicholas Daggeworth seized the manor of Swords as Commissioner of Forfeitures, on the plea that the conditions above stated had not been complied with. He, however, afterwards confessed that the charge had not been proved, and therefore a writ of restitution was issued by the Treasurers and Barons of the Exchequer to Robert de Wykeford, Archbishop of Dublin. The great prelates seem to have lived in almost royal state within their manor of Swords. They had their own seneschal, who was exempt from the authority of the sheriff of the county, and the law courts. The archbishops could try every case except the four pleas of the Crown, and their gallows was erected near the town on an eminence since known as Gallows Hill. Every writ issued from the civil courts had to be transferred to the prelates’ seneschal before it could be served. The office of chief constable of the palace was a post of considerable importance, and survived the occupation of the castle for a considerable time. William Galrote held the position in 1220, Sampson de Crumba in 1240, and Thomas Fitzsimons in 1547. In 1624 we read that Patrick Barnewell, of Grace Dieu, received pardon for alienation of certain interests, amongst which was the Constableship of Swords with ten acres in the Broad Meadow that belonged to the office. It was most likely in connection with this post that the Lords of Kingsland were required to attend the Archbishop whenever he visited Swords, and to hold his stirrup as he mounted or dismounted, for which service they held lands to the value of some £300 a year. It seems to be uncertain at what exact period the castle ceased to be used as a residence by the Archbishops, but in 1324 Alexander de Bicknor built the archiepiscopal palace of Tallaght, which was used as a country seat for the Archbishops for centuries, and only ceased to be considered as a palace in 1821.
