Trinity College, Dublin, corporately designated as the Provost, Fellows and Scholars of the College of the Holy and Undivided Trinity of Queen Elizabeth near Dublin, was founded in 1592 by Queen Elizabeth I, and is the only constituent college of the University of Dublin, Ireland's oldest university. Trinity is located on College Green opposite the former Irish Houses of Parliament (now a branch of the Bank of Ireland). The campus occupies 47 acres (190,000 m�), with many attractive buildings, both old and new, centred around large courts and two playing fields.

The college and university are effectively one, and as such are often referred to collectively as the University of Dublin, Trinity College. The main exception to this is the conferring of degrees; the college provides all the programmes and academic staff are members of it, but the university confers the degree.
