Historically the site of a Viking settlement, Waterford's medieval defensive walls and fortifications include the 13th or 14th century Reginald's Tower. The medieval city was attacked several times, and earned the motto Urbs Intacta Manet ('The Untaken City'), after repelling one such 15th century siege. Waterford is known for its former glassmaking industry, including at the Waterford Crystal factory, with decorative glass being manufactured in the city from 1783 until early 2009 when the factory closed following the receivership of Waterford Wedgwood plc. The Waterford Crystal visitor centre was opened, in the city's Viking Quarter, in 2010 and resumed production under new ownership. As of the 21st century, Waterford is the county town of County Waterford and the local government authority is Waterford City and County Council.

Located near an earlier settlement, Galway grew around a fortification built by the King of Connacht, Tairrdelbach Ua Conchobair in 1124. A municipal charter in 1484 allowed citizens of the by then walled city to form a council and mayoralty.

Following a period of decline, as of the 21st century, Galway is a tourist destination known for festivals and events including the Galway International Arts Festival.
