Halnaker Windmill and WWII anti aircraft battery

Halnaker windmill was built in 1750 by the Duke of Richmond and Gordon. She stands at a height of 400 feet (121 metres) above sea level on the South Downs near Chichester and hasn't milled corn since 1905, when she was badly damaged during a storm.

She is one of the oldest surviving windmills in Sussex and was once painted by Turner himself.

Close by, to the east and to the north east are two WWII anti aircraft batteries
