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 located in Dublin, Ireland. 

The college was founded in 1592 by Queen Elizabeth I as the "mother" of a new university.  It is one of the seven ancient universities of Britain and Ireland, as well as Ireland's oldest surviving university. 

Trinity College is widely considered the most prestigious university in Ireland and amongst the most elite in Europe, principally due to its extensive history, reputation for social elitism and unique relationship with both the University of Oxford and the University of Cambridge.  Trinity College is now surrounded by central Dublin and is located on College Green, opposite the historic Irish Houses of Parliament.
