The previous capital of Palau was located provisionally in Koror. The
Constitution of Palau, ratified in 1979, directed the
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. Further work was not begun until the early 2000s when Palau secured a $20million loan from
Taiwan as part of efforts to enhance relations between the two countries and
secure Palau's diplomatic recognition of Taiwan. Containing separate buildings for the
Olbiil era Kelulau (the country's legislature), and also the
judicial and
executive branches, connected via a central open plaza, the complex cost over
US$45million, and it was officially opened on 7 October 2006, with over 5,000 people in attendance. Government officials moved their offices from Koror to Ngerulmud shortly after. A 2013 piece in
The Wall Street Journal reported that the capitol building, which was "unsuited to the local climate", had put Palau in debt, and a fault in the ventilation system had recently caused a mold infestation. In April 2013, Ngerulmud's post office was closed permanently, as part of cost-cutting measures implemented by the postmaster, Tommy Sinsak. It had been established in December 2011, following an
Olbiil era Kelulau resolution, and was one of only two in the country (the other being in Koror). During its 16 months of operation, expenses had exceeded US$30,000, while revenues, mainly from stamps, were less than $2,000. Ngerulmud is the only settlement in Palau to have its own
ZIP code (96939), with the rest of the country using 96940 – the
United States Postal Service services Palau as part of the
Compact of Free Association with the United States. In July 2014, Ngerulmud hosted the official opening of the
45th Pacific Islands Forum. However, the majority of events at the forum were held in Koror, with the leader's retreat held in
Peleliu State. In February 2016, Ngerulmud hosted the 16th Micronesian Presidents' Summit, which was attended by the presidents of Palau, the
Marshall Islands, and the
Federated States of Micronesia. == Geography ==
