Dublin contains several notable suburbs, including Rathmines and Rathgar, where the homes of many wealthy businesspeople of Dublin are located; and Glasnevin, where the noted writers Joseph Addison, Jonathan Swift, Richard Brinsley Sheridan, and other well-known personalities once resided. In the cemetery of Glasnevin lie the remains of the Irish patriots Daniel O'Connell and John Philpot Curran.
IV. Points of InterestMany of Dublin's historic edifices are in the old section of the city, south of the Liffey. Dublin Castle, the nucleus around which the modern town developed, formerly housed the offices of the British viceroy of Ireland. Most of this structure, which occupies a ridge overlooking the river, was completed in the 16th century and later, but parts of it date from early in the 13th century. In the vicinity of the castle is the Protestant cathedral of Christ Church, founded in 1038 and rebuilt from 1870 to 1877 according to the original design. Saint Patrick's Cathedral, a Gothic structure not far from Christ Church, is the largest of the many churches in Dublin and the center of the Protestant faith in the country. Sometimes called the Westminster of Ireland, the cathedral was founded in 1190 and rebuilt between 1220 and 1260. The remains of Jonathan Swift, once dean of St. Patrick's, are interred in the cathedral. The University of Dublin and the Bank of Ireland building are in the old section of Dublin. Among other public buildings of the city are the Customs House, an 18th-century structure; the Four Courts, seat of the high courts of Ireland; and Leinster House, seat of Dáil Éireann, the lower house of the bicameral national Parliament. Dublin also has a number of notable statues commemorating such famous Irish citizens as Daniel O'Connell, the statesman and orator Edmund Burke, and the writer Oliver Goldsmith. The principal unit of the Dublin park system is Phoenix Park, in the western environs of the city.
