The principal or west front of Trinity College, looking on to Grafton Street, College Green, and the old Houses of Parliament, now occupied by the Bank of Ireland, is a Palladian façade three hundred feet in length and sixty-five feet in height, occupying the whole of the eastern side of the large paved space which is still called College Green. The centre or principal _corps de logis_ is one hundred feet in length. The entablature is supported by four detached columns with Corinthian capitals; and a bold but simple pediment surmounts the whole. At either corner is a square pilaster with a Corinthian capital. The building is continued on either side of this centre to a distance of seventy feet of plain and unadorned construction; the ground story of rustic ashlar, the remainder of fine cut granite. The north and south extremities of this great front are formed by two square pavilions rising above the height of the wings, and projecting about ten feet from the curtain line. The pavilions are pierced by four handsome Palladian windows, in the north and west and in the south and west fronts respectively; and the construction is ornamented at the projecting angles by coupled pilasters of the Corinthian order, supporting an attic story, surmounted by a very satisfactory balustrade. In the entire façade are fifty-one windows regularly disposed, giving light to four stories of rooms. According to the original plan the centre of the building was to have been crowned by a dome, and the abandonment of what might have given additional nobility to the whole is said to have been merely due to want of sufficient funds. But the elevation as it is, is not wanting in dignity; and though somewhat severe in its outlines, it gives the impression at once of simplicity without meanness, of solidity without heaviness, and of richness without extravagance of detail.
