Walbrook is a subterranean river in the City of London that gave its name to a City ward and a minor street in its vicinity. The ward of Walbrook contains two of the City's most notable landmarks: the Bank of England and Mansion House. The street runs between Cannon Street and Bank junction, though vehicular traffic can only access it via Bucklersbury, a nearby side-road off Queen Victoria Street. ==The river== The brook played a very important role in the Roman settlement of ''Londinium'', the city now known as London. The stream started in what is now Finsbury and flowed through the centre of the walled city, bringing a supply of fresh water whilst carrying waste away to the River Thames. Effectively dividing the settlement in two, it emerged just to the west of the present-day Cannon Street Railway Bridge. During Roman times it was also used for transport, with the limit of navigation some 200m from the Thames, at a point now known as Bucklersbury building. It was there the Romans built a port and temple to Mithras on the east bank of the stream.〔 The temple was found and later excavated during rebuilding work after World War II. The Roman Governor's palace was found further down the east bank of the stream, near its entry into the Thames. The etymology begins soon after Londinium was captured by the invading Anglo-Saxons during the late 6th century (also known then as ''Caer Lundein''). It is thought that the brook was named because it ran through or under the London Wall; another theory is the name comes from ''Weala broc'' meaning 'brook of the Welsh'. Walbrook formed one division in the city: Ludgate Hill to the west and Cornhill to the east.〔(London Archaeologist Spring 2003 )〕 When St. Margaret Lothbury was rebuilt in 1440, the Lord Mayor Robert Large paid for the lower Walbrook to be covered over. By the time of the first maps of the area, the "copperplate" map of the 1550s and the derivative "Woodcut" map of c.1561, the whole Walbrook within the city walls was culverted. John Stow, the historian of London, wrote about the Walbrook in 1598, saying that the watercourse, having several bridges, was afterwards vaulted over with brick and paved level with the streets and lanes where it passed and that houses had been built so that the stream was hidden as it is now.〔 The Walbrook's source was Moorfields, north of the City wall which it passed through just west of All Hallows-on-the-Wall Church.〔.〕 In the 1860s, excavations by General Augustus Pitt Rivers uncovered a large number of human skulls, and almost no other bones, in the bed of the Walbrook.〔Lewis Thorpe, ''The History of the Kings of Britain'', Penguin, 1966, p. 19〕 This has been seen as reminiscent of a passage from Geoffrey of Monmouth's ''History of the Kings of Britain'' (ca. 1136) in which a legion of Roman soldiers who surrendered to Asclepiodotus after being besieged in London were decapitated by his allies the Venedoti, and their heads thrown into a river called the ''Gallobroc''.〔Geoffrey of Monmouth, ''Historia Regum Britanniae'' 5.4〕 However, Geoffrey's ''History'' is notoriously unreliable, and some historians consider these skulls to be a result of the rebellion of Boudica.〔John Morris (1982), ''Londinium: London in the Roman Empire'' p. 111.〕 As late as the early 19th century, part of the branch that runs from Islington was open and powered a lead mill. The construction of the massive infrastructure of the London sewerage system with five main sewers incorporated many existing culverts, storm sewers, or sluices. This included the culvertized Walbrook, which by 1860 had been linked into a network of 82 miles worth of new sewerage lines, channeled to the Northern Low Level Sewer at a point near the Bank of England. Many small leaks stream into the rounded sewer for much of the year when the water table is sufficient.〔(Walbrook River from London's Lost Rivers website )〕 On 18 June 1999, during the "Carnival Against Capitalism", timed to coincide with the 25th G8 summit, fire hydrants were opened along the route of the Walbrook by Reclaim the Streets, symbolically releasing the river to "reclaim the street" from the "capitalist forces" of city growth which had subsumed it. The Walbrook is one of many "lost" rivers of London, the most famous of which is the River Fleet. It entered the Thames at Dowgate. 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「Walbrook」の詳細全文を読む スポンサード リンク
