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.
