Title:
Warsaw

Context:
After World War II, under a Communist regime set up by the conquering Soviets, the "Bricks for Warsaw" campaign was initiated, and large prefabricated housing projects were erected in Warsaw to address the housing shortage, along with other typical buildings of an Eastern Bloc city, such as the Palace of Culture and Science, a gift from the Soviet Union. The city resumed its role as the capital of Poland and the country's centre of political and economic life. Many of the historic streets, buildings, and churches were restored to their original form. In 1980, Warsaw's historic Old Town was inscribed onto UNESCO's World Heritage list.
