Liverpool is a city in North West England, along the eastern side of the Mersey River Estuary.

Built across a ridge of hills rising up to a height of around 70 metres above sea-level at Everton Hill, the city's urban area runs directly into Bootle and Crosby in Sefton to the north, and Huyton and Prescot in Knowsley to the east. It faces Wallasey and Birkenhead across the River Mersey to the west.
