Located in the southeast corner of Wales, Cardiff became the country’s capital in 1955 and The 74,200-seat Millennium sports stadium and the futuristic Wales Millennium Centre for the performing arts have now joined Cardiff Castle as the city’s star attractions. The 11th-century castle gives visitors a great introduction to Welsh history, and a climb to the top of the keep offers stunning views of the city and surrounding countryside. With its exhibits of Roman pottery and gold jewelry dating back to the Bronze Age, the National Museum Cardiff is also a must-see attraction.
