Colonel Nicholas Walker, a Cromwellian officer, lived in the castle after the Restoration. It was said that he was present on the scaffold at the execution of Charles I. with his face covered by a vizor. The Hearth Money Returns of 1664 state that Drimnagh was occupied by “Lt.-Col. -----,” and had three “smooks” or chimneys. In 1841 the fortress was the property of the Marquis of Lansdowne. It was one of the castles of the Pale, and the scene of Mr. R. D. Joyce’s romance entitled “The Rose of Drimnagh” is laid there. Until lately it was inhabited by Mrs. Mylott, but it is now empty.

[Illustration: DUBLIN CASTLE.] _DUBLIN CASTLE_ The situation chosen by the Norsemen for the first fortress of “Duibhlinn” (A.D. 840) was naturally strong, being on a hill at the junction of the Liffey and the Poddle. After this date we read of several raids upon the dun, or castle of Dublin, including the treacherous entry into the city of Milun DeCogan and Meyler Fitz-Henri during a truce, when all the defenders of the stronghold were put to the sword. This was shortly after the landing of Strongbow. The present area covered by Government buildings includes the ancient site. When Henry II. came to Dublin a large wooden hall, covered with wattles, was erected in Dame Street, that he might entertain the Irish chiefs who came to pay homage. Upon his return to England he committed “Dublin with its castle and donjon to Hugh de Laci, Fitz-Stephen, and Morice Fitz-Gerald.” Hugh de Lacy became the first Viceroy. It was while he was in England that Meyler Fitz-Henry, who had been appointed Lord Justice in his absence, wrote to King John complaining that he had no safe place to store the King’s treasure, and asking for leave to erect a proper fortress. This he received in the form of a patent dated 1204, which says:-- “But you are first to finish one tower, unless afterwards a castle and palace, and other works that may require greater leisure, may be more conveniently raised, and that we should command you so to do.”
