Shadwell is a district of East London, England, in the London Borough of Tower Hamlets, east of Charing Cross. It lies on the north bank of the Thames between Wapping (to the west) and Ratcliff (to the east). This riverside location has meant the area's history and character have been shaped by the maritime trades.
Historically a hamlet of the Manor and Ancient Parish of Stepney, it became a parish in its own right in 1670. the area of the Hamlet and Parish included areas south of Cable Street including Shadwell Basin and the King Edward Memorial Park.
In the 13th century, the area was a low lying marsh known as Scadflet, from the Anglo-Saxon fleot, meaning a shallow creek or bay. Because a spring by a church dedicated to St Chad filled a nearby well, a false etymology changed the name into Chadwelle. This changed further into Shadwell.
In 1975, archaeologists discovered evidence of a port complex between Ratcliff and Shadwell, that was used throughout Roman occupation of Britain, and being most active in the 3rd century AD. The port seems to have initially been used for seagoing ships into the City of London, which is believed to have stopped between 250 and 270AD. A water level drop meant that the port was used primarily for the public bath house near St George in the East, which existed from the first to fourth centuries. Archaeologists also found evidence of a late third-century signal tower in Shadwell. A Roman cemetery containing two coffins was also discovered in Shadwell in around 1615.
The area was part of the historic (or ancient) county of Middlesex, but military and most (or all) civil county functions were managed more locally, by the Tower Division (also known as the Tower Hamlets).
The role of the Tower Division ended when Shadwell became part of the new County of London in 1889. The County of London was replaced by Greater London in 1965.
Shadwell's eastern waterfront had been drained in the Middle Ages whilst the western waterfront had been drained during the reign of King Henry VIII, by Cornelius Vanderdelf after an Act of Parliament.
