翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Unai Lagua Japanese Defense Pillbox ： ウィキペディア英語版 Unai Lagua Japanese Defense Pillbox The Unai Lagua Japanese Defense Pillbox is one of the more unusual surviving World War II-era Japanese fortifications on the island of Saipan in the Northern Mariana Islands. It is located at the southern end of Unai Lagua (Parrot Fish Beach), which stretches along the northern shore of the island. The pillbox is fashioned out of poured concrete and coral boulders, and uses natural rock formations as part of its walls. This construction was necessitated by a severe shortage of building materials on the island as the Japanese prepared the island's defenses against the advancing Allied forces in 1943-44. The use of natural materials and terrain had the added benefit of rendering the position nearly invisible to aerial or offshore observation.〔(【引用サイトリンク】title=NRHP nomination for Unai Lagua Japanese Defense Pillbox )〕 The pillbox was listed on the National Register of Historic Places in 1985;〔 it is also a contributing element to the "Landing Beaches; Aslito/Isley Field; & Marpi Point, Saipan Island", a National Historic Landmark District encompassing surviving World War II military infrastructure on Saipan. ==See also== *National Register of Historic Places listings in the Northern Mariana Islands 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Unai Lagua Japanese Defense Pillbox」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
