This is the fourth, updated and revised edition of the best-selling three-volume original book published in 2018, 2020 and 2022. A Guide to Communist Bulgaria researches comprehensively the architectural, artistic and material heritage of the People’s Republic of Bulgaria through a rich visual presentation put in context. Included are the must-visit locations for anyone with an interest in the triumphs and failures of Bulgaria’s recent past: from Buzludzha and Dimitrovgrad to Stalinist Sofia and the monuments of the northwest. Special chapters deal with the most remarkable as well as the oddest monuments and public art samples of the Communist era, from the images of Communist guerilla fighters and Soviet soldiers to ordinary working people. The Communist regime in Bulgaria left many traces visible in modern Bulgaria. These include the abandoned military barracks and cinema theatres, and the ruins of the failed megaprojects. For anyone interested in incentive travel through the second half of the 20th and the early 21st century southeastern Europe.
