The River Dane joins the River Weaver and the Weaver Navigation within the parish. Also passing through the parish are the A533 road, the Trent and Mersey Canal, and a railway built by the Cheshire Lines Committee. Many of the listed buildings are associated with these features.
Listed buildings that were originally designed for domestic use but later converted for other purposes include Winnington Hall, and Hartford Manor. Buildings still in domestic use include Rose Cottage, Cassantree, and the cottages at 256–268 London Road. There are three listed churches, the Anglican churches of St Helen, together with the sundial in its churchyard, and Holy Trinity, and the Roman Catholic Church of St Wilfrid.

In addition the statues of Ludwig Mond and Sir John Brunner, the founders of the chemical firm of Brunner Mond, standing in front of the research laboratories of Winnington Works, are listed. The extraction of salt caused subsidence in the town towards the end of the 19th century, and buildings were designed so that they could be lifted in the event of further subsidence. Some of these are listed, namely the Brunner Public Library, the R. A. O. B. Hall, and the Post Office.
