113 THE MOSCOW KREMLIN: Russia's Fortified Heart

1-984113

Fortress series. Examines the Kremlin -- the fortified complex covering 70 acres at the heart of Moscow, behind walls up to 18m high and watched over by 20 towers, the Kremlin houses everything from Russia's seat of political power to glittering churches. This is a fortress that has evolved over time, from the original wooden guard tower built in the 11th century to the current stone and brick complex. Over the years, it's been built, burnt, besieged and rebuilt and includes today's invisible defences such as it GPS spoofing field (switch on your phone inside the walls and it may well tell you you're at Vnukovo airport, 30km away) and drone jammers.
