Denmark’s royal family on Sunday participated in a special “celebratory church service” at Aarhus Cathedral as the new King Frederik X, accompanied by wife Queen Mary and mother Queen Margrethe, waved to crowds gathered outside the 12th-century building that is the tallest church in the country. The royal family drove 3.5 kilometers (2.2 miles) through Aarhus, Denmark’s second-largest city, from royal residence Marselisborg Castle to Aarhus Cathedral.
