During the Cold War, the USSR undertook the greatest cartography operation ever known, covertly producing thousands of detailed plans of countries, towns and cities around the world. Some of these previously-restricted maps have recently become available on the open market. Informed by the work of John Davies and others, ex-NGS Chair Lex Lamb will present the fascinating story - and highlight some peculiar features of - the secret Soviet map of Glasgow. The talk will also present the first ever translation of the map's detailed text description of Glasgow's infrastructure, industry and government in the 1970s.
