[2] Before the Norman Conquest, Heswall has been cited as a possible location for Dingesmere, mentioned with regard to the Battle of Brunanburh, in Egil's Saga.

Its growth was started by wealthy merchants from Liverpool; they had originally chosen it as a retreat, but the arrival of two railway connections allowed them to commute.

The previous church was destroyed[citation needed] by a violent thunderstorm on 19 September 1875; the organist and the boy who pumped the bellows for the organ were both killed.

[5] It stood on the opposite side of Telegraph Road from The Puddydale'’ and had a clock tower and grounds with views over the Dee estuary.

An affluent area, Heswall was listed as the seventh richest neighbourhood in the UK in 2001, with an average household income of £46,600.

[7][needs update] In 2022, the median house price in Heswall was £409,500, making it the most expensive in the Wirral area.

It has the status of both Site of Special Scientific Interest (SSSI) and Local Nature Reserve (LNR).

Other open areas also overlooking the Dee are the Beacons, and Poll Hill, which is the highest point on the Wirral Peninsula.

[10] It was originally on the eastern edge of The Puddydale, opposite the Royal Liverpool Children's hospital on Telegraph Road (now converted into a local Tesco).

The main bus operators are Arriva North West, Stagecoach Merseyside & South Lancashire, Al's Coaches, A2B Travel and Aintree Coachlines.

[13] Heswall railway station is a stop on the Borderlands Line, which connects Bidston with Wrexham Central.

Heswall F.C., founded in 1891, play at Gayton Park on Brimstage Road and competes in the West Cheshire Association Football League.

Heswall Village Fete is the scene for Coldplay's "Life in Technicolor II" music video.
