The National Parliament house, located on the hill above Hibiscus Avenue, built with American aid, is a concrete structure of conical-shape, which was inaugurated in 1993. The dome has tapestry, frescoes, and traditional artwork. The parliament building was built at a cost of US$5 million in honour of the 450 U.S. soldiers and 1,200 Marines who died during the Guadalcanal operations during the war. Ironically the building was originally built by a Japanese firm.
