Trinity College is the sole constituent college of the University of Dublin, a research university in Ireland. The college was founded in 1592 as the "mother" of a new university, modelled after the collegiate universities of Oxford and of Cambridge, but, unlike these, only one college was ever established; as such, the designations "Trinity College" and "University of Dublin" are usually synonymous for practical purposes. It is one of the seven ancient universities of Britain and Ireland, as well as Ireland's oldest university.
