DUBLIN, TRINITY COLLEGE: One of the highlights of any Dublin tour is the campus of the distinguished Trinity College, an originally Protestant institution where many of the most famous figures in Irish arts and history have studied. Among writers, its students have included Jonathan Swift, Oliver Goldsmith, Oscar Wilde and Samuel Beckett (Joyce, however, studied at University College, Dublin, a Jesuit institution). The theater building is named after Beckett, and the visitor will note many other famous names affixed to rooms and buildings. The 19th-century Campanile at the center of campus; in the background, the oldest buildings on campus, the early 16th century Rubrics, now used as residence halls.
