Halnaker Windmill, Grade II listed tower mill in Boxgrove, England.
Halnaker Windmill is a freestanding brick tower on a hilltop near Boxgrove in West Sussex, fitted with an octagonal metal cap and the stumps of its original sweeps, but empty inside with no floors or machinery remaining. The tower rises to about four stories and is visible from a distance, as it sits on one of the higher points in the surrounding area.
The mill was built in the early 18th century for the Goodwood Estate and ground grain for the surrounding communities for well over a century. A lightning strike in 1905 destroyed much of the wooden structure inside and brought its working life to an end.
The mill takes its name from the nearby hamlet of Halnaker, an Old English word meaning roughly 'half enclosure', hinting at how the land was divided in early medieval times. Today, visitors walk up to the tower and can peer through the gaps to see the bare interior, stripped of all its working parts.
The mill is reached on foot from Boxgrove along marked paths through gated farmland, with a steady uphill walk that is manageable but calls for sturdy footwear. The site itself is freely accessible, though the paths can turn muddy in wet weather, so it is worth checking conditions before heading out.
A short walk from the tower, traces of World War II bunkers survive where military personnel once tracked aircraft radio signals along the South Coast. These low concrete structures are easy to miss in the long grass, but they sit in plain sight once you know where to look.
