Parts of Sefton go back to the Domesday Book but the borough was officially formed on April 1, 1974.
From Southport in the north down to Bootle in the south, the area is a mix of lush coastline, farmland, industrial areas and villages. The building of the Liverpool-Southport railway in 1850 saw its popularity rise, with wealthy merchants and the emerging middle class moving to the coastline.
The borough was named after the ancient village of Sefton. When it was created, a name was sought that would not identify it with the former county boroughs of Bootle or Southport.
