The house today contains a vitally important and almost complete collection of one family's occupation for three hundred years. In the Gun Room can be found one of the largest surviving 18th century wallpaper schemes surviving in the UK (Chinese wallpaper from the 1720's), along with a "long gun" dating to about 1680 which was presented to Alderman James Lenox after the Siege of Derry. Present is a six-inches-long muzzle-loader and two late 18th-Century blunder busses. The Library contains one of the most important collections of 17th and 18th century books in Ireland and is composed of around 3000 volumes, the oldest of which is a small Latin psalter of 1541.
