Ked er a Ngchebakl, Ngchesar

Ked er a Ngchelbakl, Kaliol
( Japanese Anti-Aircraft Gun )
HIstoric Remnants of World war II


Site Type: Historic Remain WWII

Location: Ked er a Ngchelbakl, Ngchesar

Date Registered: May 24, 2005

Site No: B:NC-9:1


In recognition of its significance, Ked er a Ngchelbakl ( Japanese Anti-Aircraft Gun ) has been listed on the Palau Register of Historic Places on May 24, 2005. Through preservation, study, and interpretation, the site can serve to educate future generations concerning the historical and cultural heritage of the Palauan people and the Ngchesar state. During World War II, the Japanese military fortified Ngchesar in anticipation of the American invasion of Babeldaob. The Japanese constructed numerous gun emplacements and dug defensive trenches on the savanna ridge of Ked er a Ngchelbakl. This to show that these historic remains of World War II are in need of preserving and that there is evidence shown that Ngchesar state was included in the World War II battlefield. 

According to the survey collected by the Bureau of Arts and Culture in Ngchesar from the year 2001, they identify this historic site as Ked er a Ngchelbakl known as site number B:NC-9:1. Because of its significance, the site contains many Japanese Anti-Aircraft gun dating World War II. The site is located on a savanna area between two rivers that connected to one before flowing into Ngerdorch river near the Shimizu plantation. The guns are inside a trench with an extension that goes to the edge of the forest. The gun is rusty but still intact. The name of the ridge is Ked er a Ngchelbakl but because of the gun, locals referred to the ridge as Ked er a Kaliol. 

This historic World War II site also contains a trench from the bunker that connects northeast downward toward the forest. This trench is a path for the Japanese soldiers to travel from the forest to the anti-aircraft gun as a hideout from incoming enemies. The elders of this village called them trench of Babeldaob, that was dug up by the Japanese soldiers. A visual measurement was conducted that the width of the trench is about two to three feet (2-3 feet) and the depth is about three to five feet (3-5 feet) from top to bottom. The trench identified on site is in good condition. These are the military installations used by the Japanese soldiers on the savanna area in which its historic remains are still intact until today.

FY’20 Site Rehabilitation and Conservation Project 

The site rehabilitation and conservation project of Ked er a Ngchelbakl, Kaliol ( Japanese Anti-Aircraft Gun ) located in Ngchelbakl region commence on June 07, 2022 and completed on July 15, 2022. The project involved clearing overgrowth trees, vines, and bushes around the site. Thet accomplish by removing moss, dirt and rusts from the anti-aircraft guns and apply a stop rust clear paint in order to prevent the WWII remains from corroding. Other modification such as digging the trench are supervised by village elders and monitored by the Bureau. They also built a 3ft. x 4ft interpretive signboard using traditional materials at the site.

The main purpose of this project is to educate and motivate the public, especially the affected villagers to realize the importance of the site and its potential economic benefits. Through the project, the concerned executives, traditional leaders and individuals could be reminded once again that these precious resources are theirs and should be maintained for many reasons: for present and future generations to learn and enjoy; for continuous education; for heritage tourism; and for economic development.

Governor Duane Hideo and the community of Ngchesar State feel fortunate to have one of their precious sites rehabilitated and have access for visitors. They believe that this is one way for others to learn about their state’s history and thanked the Bureau of Cultural and Historical Preservation under the Ministry of Human Resources, Culture, Tourism and Development for their on-going efforts in helping small communities little by little with their financial assistance.
