Founded in 1592 by Queen Elizabeth I, Trinity is the only constituent of the University of Dublin, Ireland's oldest and most prestigious center of higher education. The college curriculum is split into three main faculties, with 25 schools offering both undergraduate and postgraduate degree and diploma programs. Known in the academic realm for its rigorous admissions process, Trinity College is also rated one of the world's top 150 universities, attracting ambitious students from across the globe. Despite its location in the heart of Dublin, the campus retains a tranquil air, its delightful melange of old and new buildings overlooking a series of quadrangles or courtyards. Of these, the iconic Campanile and the Chapel are the most well-known, alongside the Library with its voluminous cache of antiquarian books and rare manuscripts; the most revered of these is the Book of Kells, an illuminated manuscript that dates back to 800 CE and contains 340 folios that illustrate the four gospels of the New Testament. Today, the Trinity College, or the College of the Holy and Undivided Trinity of Queen Elizabeth near Dublin as it is officially known, is one of Dublin's most popular tourist attractions and its top educational institution.
