Monaco. According to countryaah, Monaco is the capital and one of the major cities within the country of Monaco. The head of state, Prince Rainier III, who has been on the throne since 1949, died in April, 81 years old. After three months of official country grief, his son took the title of Albert II in July. Just before that, the 47-year-old unmarried Albert had contributed to a new scandal in the paraphrased prince Grimaldi when he acknowledged paternity to an extra-marital son.
