Trinity College, officially The College of the Holy and Undivided Trinity of Queen Elizabeth near Dublin, is the sole constituent college of the University of Dublin, a research university in Dublin, Ireland. Queen Elizabeth I founded the college in 1592 as "the mother of a university" that was modelled after the collegiate universities of Oxford and Cambridge, but unlike these affiliated institutions, only one college was ever established; as such, the designations "Trinity College" and "University of Dublin" are usually synonymous for practical purposes.
Trinity College Dublin is a sister college to St John's College, Cambridge and Oriel College, Oxford, and by incorporation, a graduate of Dublin, Oxford or Cambridge can be conferred the equivalent degree at either of the other two without further examination. The university is legally incorporated by "the Provost, Fellows, Foundation Scholars and other members of the Board," as outlined by its founding charter. It is one of the seven ancient universities of Britain and Ireland, as well as Ireland's oldest surviving university. The college's main campus, in the heart of Dublin, has often been ranked among the most iconic in the world, and is the setting for a number of novels, films and urban legends.
