One whiff of the ancient books in Trinity College Library (www.tcd.ie) is enough to make you ditch your tablet—at least for a while. The magic continues at Sweny's Pharmacy (www.sweny.ie), a time-capsule spot where prescriptions have given way to bookshelves. James Joyce fans and local enthusiasts gather here for dramatic readings of Ulysses—the novel's hero once bought lemon soap from these very shelves. I've even joined in, reading a passage in French. It's an unforgettable experience. Don't miss the Little Museum of Dublin (www.littlemuseum.ie), which brings the city's history to life through everyday objects donated by residents. Upstairs, a dedicated room celebrates the iconic Irish band U2, leaving you humming "With or Without You" as you go.
