Historically known as; Heleshala, Herleshala, ; Haleshal, 1224; Haleshale, 1275; Halsale, 1278; Halshale, 1292; Halleshale, 1332; Halsall, xv century. Halsall is a large ancient parish which grew from being a small farming settlement; reflecting this background, much of the land area of Halsall is sparsely populated with many isolated dwellings. The land area of Halsall extends quite a way towards Ainsdale along Carr Moss Lane, to a point where the border is closer to Ainsdale village centre than it is to Halsall. Halsall village is centred around St Cuthbert's Church and the war memorial. The church dates from the 14th century and the Rector is the Rev. Paul Robinson. The hall is to the south-west of the church; between them was a water-mill, taken down about 1880. Near the site of the water mill now stands the former Halsall Arms public house. There is a junior school, St Cuthbert'sChurch of England Primary School with around 140 pupils from age 4 to 11. The Saracen's Head is a large public house on the banks of the canal. There is also a garage, offices and a red telephone box situated by the former post office. The church and much of the village stand on a rocky ridge, in marked contrast to the low-lying flat peat mossland between the ridge and the sand of Ainsdale and Birkdale. There are several listed buildings in Halsall including the Grade I listed church including Halsall Hall and a number of listed canal bridges amongst other structures. Halsall Hall still stands, but it has been subdivided into a number of dwellings. In 2011, the parish had a population of 2,057 and covered an area of. A natural curiosity of the district was the bituminous turf which was found in the Halsall moss. This was known as Lit-turf and could be burnt like a candle.
Halsall is where the first sod was ceremonially dug for the commencement of the Leeds and Liverpool Canal. A sculpture just across the bridge from the Saracen's Head pub now commemorates this. The canal in this area was partially fortified with pillboxes and anti tank measures as it formed part of Stop Line 14 in WW2.
Halsall plays host to the annual scarecrow festival. The festival runs from June to July. The official route for the scarecrow festival was down the main road through the village but the scarecrows have spread to the surrounding areas. The scarecrow festival is not a competition.
