As you can see, there are 45 hillforts listed in the Wiltshire HER database. These range from the magnificent Old Sarum, to the now obliterated Nun's Walk Area. Have a browse through the links below - each will take you to an individual page which will display a close up satellite image of the hillfort in question, and also the relevent HER data for that monument. The maps are downloadable as a .kmz file from each page.
At the bottom of each page is a list of recommended books on the subject of Iron Age fortifications - these have been hand picked for usefulness to the general reader - the list is not auto-generated. The links will take you to the Amazon page for that book, and if you make a purchase you will be helping to support Digital Digging. Thanks in advance, should you decide to go down that route.
