Excellent- even more concrete for me to visit this summer! "A series of previously unknown sites set up to defend Scotland from attack during the First World War have been revealed. An audit by Historic Scotland to identify war-time heritage in the lead up to the centenary of the war later this year identified 900 buildings and places that were used for training or defence during the war, more than three times the number expected at the outset of the audit. Plans to protect Edinburgh from any potential invasion were particularly extensive. War Office maps that were found in the audit showed a network of trenches and strongpoints at Portobello that stretched from the shore of the River Forth to the south of the city to prevent a land attack. Among the records that have been added to or updated in the audit are 239 hospitals ranging from village halls to existing medical centres, 39 prisoner of war camps in Hawick, Edinburgh Castle and the island of Raasay, and 350 drill halls established to train volunteer soldiers. Historic Scotland and the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) will designate some of the remaining sites to recognise and protect their significance during the centenary of the First World War." http://www.guideandgazette.co.uk/news/scottish-headlines/war-time-heritage-sites-uncovered-1-3300179
