The fort is situated on the end of the inner breakwater, which abuts from the dockyard of the harbour, on the northern face of the island. It was constructed between 1859-1862, and is 100 ft in diameter. In September 1978 the inner breakwater became Grade II Listed, and this designation includes the fort. ==History== In effort to protect Portland Harbour an array of various defences were created, including the Inner Pierhead Fort, a coastal artillery battery. It was designed by the Admiralty in 1859, with construction commencing that same year. Initially it was undecided on whether the fort should be built with Portland stone or granite. The army built two butt walls, one of Portland stone, and the other granite. HMS ''Blenheim'' used heavy fire upon these walls, and Portland stone proved to be stronger, and was chosen as the building stone. The fort was completed during 1862. In 1892 it was reported that the battery was armed with eight 64-pounder guns. With the need for anti-torpedo defences, the fort had two 12-pounder quick-firing guns installed by 1902. Although the Inner Pierhead Fort had seen little use since the time of World War I, it was equipped with a 40 mm Bofors gun during the course of World War II. As the 20th-century progressed the fort fell into total disuse and has never been opened to the public. In 1996, the Royal Navy left Portland Harbour, and Portland Port Ltd became the new owners, turning the harbour into a commercial port. There were published reports that year revealing possible plans of the renovation of historic coastal fortifications in the area, however this never materialised for any of the harbour's historic sites, including the Inner Pierhead Fort.〔http://www.independent.co.uk/news/portlands-naval-history-ends-as-last-warship-sails-1592621.html〕 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「Inner Pierhead Fort」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.
