In 1991 the Dublin Writers Museum was opened to house a history and celebration of literary Dublin. Situated in a magnificent 18th century mansion in the north city centre, the collection features the lives and works of Dublins literary celebrities over the past three hundred years. Swift and Sheridan, Shaw and Wilde, Yeats, Joyce and Beckett are among those presented through their books, letters, portraits and personal items. The museum holds exhibitions and readings and has a special room devoted to childrens literature.
