"Trinity College Pass through the iconic arched doorway at College Green and enter the elegant quads, handsome architecture and verdant lawns of Trinity College, one of Ireland 's most prestigious universities. Among its many attributes is the atmospheric 18th-century Old Library, whose most precious tome is the 1,200-year-old Book of Kells, a priceless illuminated manuscript. Also worth a visit are the college's Douglas Hyde Gallery, devoted to contemporary art, and the thought-provoking Science Gallery."
