[[Mill Hill, Shoreham|Mill Hill]] ({{gbmappingsmall|TQ 212 071}}) is also known as Shoreham bank, as the hillside falls sharply to the [[River Adur]]. It is a [[Local Nature Reserve]] and has been famous for its butterflies since the 1820s.<ref name=":1">{{Cite web|title=Mill Hill & the Butterflies|url=https://www.glaucus.org.uk/MillHill2009Article.htm|access-date=2022-01-08|website=www.glaucus.org.uk}}</ref> In May, the hillside is dusted yellow with [[horseshoe vetch]]: the butterflies' food plant. In August, the hillside is colourful with knapweeds, pink [[Centaurium erythraea|centaury]], the tiny white pinpoints of [[eyebright]], and the white umbels of [[wild carrot]], [[Pastinaca sativa|wild parsnip]], [[St John's wort]], and [[wild thyme]].<ref>{{Cite web|title=Mill Hill LNR|url=https://designatedsites.naturalengland.org.uk/SiteLNRDetail.aspx?SiteCode=L1009032&SiteName=&countyCode=46&responsiblePerson=&SeaArea=&IFCAArea=|access-date=2022-01-08|website=Natural England - Designated Sites}}</ref> The Hill is known for its [[dingy skipper]]s and grizzled skippers in the spring, and in summer the [[chalkhill blue]] and [[Adonis blue]] are 'flagship' species of this Hill.<ref name=":1" /><ref>{{Cite web|last=Knight|first=Colin|date=August 2017|title=Mill Hill - Walking the Line|url=https://www.sussex-butterflies.org.uk/features/archives/2012-mill-hill.php|access-date=2022-01-08|website=Butterfly Conservation - Sussex Branch}}</ref>

From Mill Hill it is possible to see Applesham Farm, which was a village at the time of the Domesday Book in 1086. To the north end is another Saxon farm, Old Erringham, which King Alfred's successors fortified to defend the estuary. To the south is the Norman church of Old Shoreham, almost on the banks of the Adur, and next to it are the wooden piers of the 1781 toll bridge, which collected traffic tolls up to the 1960s.<ref name=":0" /><sup>:203</sup>

Mill Hill now suffers from [[Noise pollution|traffic and aircraft noise]]. The special mosses and lichens have gone, and the [[Helicella itala|Heath]] and [[Monacha cartusiana|Carthusian]] snails are now gone. Despite efforts by volunteers and rangers, the hill still carries far too great an area of dense and simplified scrub, which has flourished at the expense of the biodiverse turf.<ref name=":0" /><sup>:203</sup>
