||This iconic Sussex landmark, perched on Halnaker Hill and
visible from a wide surrounding area, is well worth the climb to
admire close up. The wildflower-rich chalk grassland at the
hilltop is a great spot to get away from it all and enjoy fine
views of the coast across a patchwork of woods and farmland. You
may see the Isle of Wight and Portsmouth’s Spinnaker Tower.

What's at Halnaker Windmill?
Halnaker Hill is a Scheduled Ancient
Monument as it is the location of a Neolithic earthwork structure
known as a Causewayed Enclosure. Within the Windmill site
there is the Windmill, a grade 2 listed building, and a WW2
Observation Post which are also protected under the SAM
The chalk grassland within the West Sussex
site is subject to a conservation cut each year. The cutting from
this are removed from the site in order to remove nutrients from
when the site was farmed and promote greater plant diversity
Enjoy the colourful flowers which thrive
amongst the chalk grassland. You may find some less common species
such as bee orchid and white horehound. Chalk downland is a rich
habitat for insects and a food source for farmland birds such as
the lovely yellowhammer. Look out for Buzzards soaring over the
landscape. Skylarks may be singing overhead - one of the
quintessential sounds of the English countryside.
Butterflies attracted to the flowers up here
include the marbled white, common blue, large skipper and red
admiral. Along the lane on the way up keep an eye out for
silver-washed fritillary, large, small and green-veined whites,
meadow brown, ringlet and gatekeeper.
