We have a chat with Simon Green - "The Blockhouse Guy". Simon has authored two books on the blockhouses of the Anglo-Boer War - a very handy field guide, as well as a more in-depth analysis of the engineering behind these 9000+ structures the British Military left behind in South Africa. We have digitised the field guide - so if you are looking to visit a Blockhouse - the Road Trip app will get you there. The Road Trip SA app is available for download Do you want to visit and explore South Africa? Touch Africa Safaris
