During World War I, Australian troops staying at nearby Hurdcott Camp carved a gigantic map of Australia into a Wiltshire hillside. Chalk gravel was used to fill shallow trenches to create an outline map some 150 feet wide with 18-foot-tall letters. Since then, despite a restoration in the 1950s and its designation as a Scheduled Ancient Monument, the map has faded, but for the past four years the Map of Australia Trust has been working on restoring the map. It was finished in time for Armistice Day. More from BBC News (video) and Historic England. [Jonathan Potter]
