What is "wallend"

Wallend (sometimes spelt as Wall End) is a locality in London's East End, located in the borough of Newham. It is a little-used name for the area lying to the north of Beckton between Barking and East Ham. The name stems from an embankment wall that was formerly used to prevent flooding from the river Roding at the 'end' of East Ham. Much of the area consists of terraced housing dating from the building-boom of the late 19th century.
