Relocation of sports teams in the United Kingdom
Arsenal was founded at Woolwich in 1886. But In 1889, Woolwich became part of London, with the formation of London County Council. Arsenal moved from Woolwich in south London to Highbury in north London in 1913. They moved again to Holloway, a neighbourhood adjacent to Highbury, in 2006, though this was a much shorter distance than they had moved when relocating 93 years earlier, and kept the club in the London Borough of Islington.
North Woolwich
The parish of Woolwich developed from the manor, and administered North Woolwich until 1888 when it was replaced by the Metropolitan Borough of Woolwich and made part of the new County of London. The neighbouring areas' local authorities of East Ham, West Ham and Barking, while also heavily urbanised, were excluded from the new London authority to remain in Essex; and so North Woolwich remained an anomaly at county level.
