Londonderry
Also known as Derry, Londonderry is one of Europe’s best-preserved walled cities and the only one in Ireland completely intact. Within the 400-year-old walls stand landmarks like the 17th-century St. Columb’s Cathedral, the imposing neo-Gothic Guildhall and the Tower Museum, which illuminates over 14 centuries of history. Evocative murals in the Bogside neighborhood acknowledge the turbulent period of the Troubles in the past, while the modern Peace Bridge symbolizes hope for a harmonious future.
