The mansion stands on the east side of Grafton Street, about twenty yards from the western side of the Parliament Square. The main entrance is from Grafton Street, through a spacious courtyard, enclosed by a granite wall 310 feet in length, and is entered by a handsome gateway. There is a private corridor, or covered way, which connects the house directly with Parliament Square within the walls of the College. The façade is of granite, finely ashlared. The ground story is of icicled and rusticated work, over which a range of Doric pilasters, with their architrave, frieze, and cornice supporting a high pitched roof with no eave. In the principal story are five windows, with balusters beneath, arranged two on either side of a large Venetian window, with columns and ornaments of the Tuscan order. The interior of the house is original and interesting; the hall and ante-hall are spacious and dignified; the circular staircase, which is lighted by a lofty domed skylight, leads up to a fine suite of apartments. On the ground floor, with an entrance from the hall, and approached through an ante-room, is the large dining-room, which is now used as the Provost’s Library and as the Board-room, where the Provost and Senior Fellows assemble in council to deliberate upon the administration and government of the College. In this room and in the ante-room is a collection of portraits of all the Provosts, from the time of Adam Loftus to Dr. MacDonnell, and of many of the distinguished Fellows and Professors of the College, and other important personages connected with the University. On the staircase is a portrait of George I., by Sir Godfrey Kneller; another of George III., by Allan Ramsay; and one of Hugh Boulter, Archbishop of Armagh, painted by Bindon for the Foundling Hospital. All these are full-length portraits. The most interesting picture in the house is, perhaps, a half-length portrait of Queen Elizabeth, by Zucchero, hanging in the large drawing-room; where there is also a full-length portrait by Gainsborough--the artistic gem of the collection--of John Russell, Duke of Bedford, Lord Lieutenant of Ireland, 1757, and Chancellor of the University of Dublin. There is also in the drawing-room a half-length portrait of Archbishop Ussher, one of the earliest Fellows of the College (Professor of Divinity, 1607; Vice-Chancellor of the University, 1614; and Archbishop of Armagh, 1624), and buried, like Primate Boulter, in Westminster Abbey. In the Provost’s apartments on the ground floor is a picture of Adam Loftus, Archbishop of Dublin and Lord Chancellor of Ireland, 1567, and first Provost of Trinity College, 1592, by an unknown artist, as well as a copy of the same by Cregan; and a head of Archbishop Ussher. There are two portraits said to be of Samuel Winter, the Puritan Provost appointed by Cromwell in 1562, but possibly portraits of Luke Challoner, one of the more distinguished founders of the University.
