In September 1975, Papua New Guinea became an independent country with Port Moresby as its capital city. Prince Charles, Prince of Wales, represented the Queen of Papua New Guinea at the celebrations. New government, intellectual and cultural buildings were constructed in the suburb of Waigani to supplement and replace those of downtown Port Moresby. They included those for government departments, including a National Parliament Building, which was opened in 1984 by Prince Charles and blends traditional design with modern building technology.
