The previous capital of Palau was located provisionally in Koror. The country's constitution, ratified in 1979, directed the Palau National Congress to establish a permanent capital in Babeldaob within ten years of the constitution's effective date. The new capital's planning began in 1986, when a contract for the construction of the capitol complex was assigned to a Hawaii-based architecture firm, Architects Hawaii Ltd. (AHL), which had previously designed the capitol complex of the Federated States of Micronesia, located at Palikir. Progress was slow, as Palau lacked engineers and architects, and most of the construction materials had to be imported.
