Long Knoll (grid reference ST794376) is just to the south of Maiden Bradley and has long been a visible milestone to me on the way down to Stourhead. When walking in the landscape around there, I have often taken photos of it and use it as an orientation point when walking. It is a distinctive ridge of chalk grassland which is about a mile in length and looks like a spine. There are fine views of it from White Sheet Hill and King Alfred's Tower, but it is not easily accessibl

White Sheet Hill is another fine example of elevated chalk grassland which has evidence of ancient history at its summit. While I have already visited plenty of dramatic hill fort sites in Wiltshire, White Sheet Hill is interesting for its diverse archaeological heritage. It has a neolithic enclosure dating back to 3,000 BC, and an Iron Age hill fort at the top. There are also Bronze Age barrows, some of which are clearly visible. It is incredible to think they have survived
