Mill Rock is a small unpopulated island between Manhattan and Queens in New York City, in the state of New York. It lies about off Manhattan's East 96th Street,〔("Mill Rock Park", New York City Department of Parks & Recreation )〕 south of Randalls and Wards Islands, where the East River and Harlem River converge. The island forms Census Block 9000 of Census Tract 238 in New York County. (Except for Mill Rock Island, Census Tract 238 consists entirely of Roosevelt Island.) Its official area is 16,173 square meters, or . This area was infamous as a treacherous area for shipping vessels to pass, and was known as the Hell Gate. ==History== Originally two smaller islands, in 1664, William Hallet bought them from the local tribes. In 1701, John Marsh built a mill on one them and the islands came to be called Great Mill Rock and Little Mill Rock.〔 The island was later squatted on by Sandy Gibson, who operated a farm on the island. During the War of 1812, the War Department built a blockhouse with two cannons on Great Mill Rock. This fortification was part of a chain of blockhouses that was intended to defend New York Harbor and protect the passage into Long Island Sound from the British Navy.〔 In 1885, the United States Army Corps of Engineers detonated 300,000 lb (136,000 kg) of explosives on adjoining Flood Rock; that island had been the most treacherous impediment to East River shipping. It was, most likely, the most forceful explosion in New York City's history at the time; it was felt as far away as Princeton, New Jersey.〔(【引用サイトリンク】title=Mill Rock Island - Historical Sign )〕 The explosion has been described as "the largest planned explosion before testing began for the atomic bomb", although the detonation at the Battle of Messines (1917) was larger. In 1890 the Flood Island remnants were used to fill the space between Great and Little Mill Rocks, producing Mill Rock.〔 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「Mill Rock」の詳細全文を読む スポンサード リンク
