Port Moresby, is the capital and largest city of Papua New Guinea. It is located on the shores of the Gulf of Papua, on the southeastern coast of the island of New Guinea. The Motuan people of the area now known as Port Moresby traded their pots for sago, other food and canoe logs, sailing from Hanuabada and other villages built on stilts above the waters of the bay. They also intermarried with the Gulf people and created strong family and trade links. New government buildings were constructed at Waigani to house government departments, including a National Parliament Building, which opened in 1984 and blends traditional design with modern building technology. The PNG National Museum and National Library are also located at Waigani.
