Theodore Roosevelt Island is a island and a national memorial located in the Potomac River in Washington, D.C.〔(【引用サイトリンク】 title=Listing of area as of 09/30/2005 )〕〔(【引用サイトリンク】url=http://www.nps.gov/this/index.htm )〕 The island was given to the American people by the Theodore Roosevelt Association in memory of the 26th U.S. president, Theodore Roosevelt; before that, the island had been known as ''My Lord's Island'', ''Barbadoes Island'', ''Mason's Island'', ''Analostan Island'', and ''Anacostine Island''.〔(【引用サイトリンク】title=Theodore Roosevelt Island )〕 The island is maintained by the National Park Service as part of the nearby George Washington Memorial Parkway.〔 The land is generally maintained as a natural park, with various trails and a memorial plaza featuring a statue of Roosevelt. No cars or bicycles are permitted on the island, which is reached by a footbridge from Arlington, Virginia, on the western bank of the Potomac. A small island named "Little Island" lies just off the southern tip; Georgetown and the John F. Kennedy Center for the Performing Arts are across the main channel of the Potomac to the north and east, respectively. ==History== The Nacotchtank Indians, formerly of what is now Anacostia (in Washington, D.C.), temporarily moved to the island in 1668, giving its first recorded name, "Anacostine." The island was patented in 1682 as Anacostine Island by Captain Randolph Brandt (or Brunett), who left the island to his daughter Margaret Hammersley, upon his death in 1698 or 1699. The island was acquired by George Mason III in 1724.〔James W. Foster, "Potomac River Maps of 1737 by Robert Brooke and Others," ''William and Mary College Quarterly Historical Magazine'' 2nd Ser., Vol. 18, No. 4. (October 1938), 410.〕 George Mason IV acquired the island in 1735 upon the death of his father and John Mason, the son of George Mason IV, inherited the Island in 1792 and owned it until 1833.〔 John Mason built a mansion around 1796 and planted gardens there in the early 19th century. The Masons left the island in 1831 when a causeway stagnated the water. Following Mason's death in 1842, John Carter acquired the land.〔 After Carter died in 1851, the island passed to William A. Bradley.〔 The island has been uninhabited since the Masons left, aside from a brief period in the Civil War when Union troops were stationed there. Locals continued to call it "Mason's Island" until the memorial was built there. In 1869, a fire destroyed the mansion's interior; around 1906, another fire caused the roof to collapse.〔 Following the declaration of war against Spain in 1898, the island was used as a test site for a number of private experiments in electrical ignition of the explosives dynamite and jovite led by the chemist Charles Edward Munroe of Columbian University. Monroe's experiments, which explored the use of the explosives for mining waterways and roadways and preparing ground for rapid entrenchment, were conducted in secret and without alerting the District of Columbia Police Department, which investigated citizens' reports of Spanish spy activity and found the explosives and detonators buried on the island.〔 From 1913 to 1931, the island was owned by the Washington Gas Light Company, which allowed vegetation to grow unchecked on the island.〔 By 1935, the Civilian Conservation Corps had cleared much of the island and pulled down the remaining walls of the house; today, only part of the mansion's foundation remains. 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「Theodore Roosevelt Island」の詳細全文を読む スポンサード リンク
