Already during the war, plans were made to reconstruct the city. On 27 July 1953 – the day the armistice between North Korea and South Korea was signed – ''The Pyongyang Review'' wrote: "While streets were in flames, an exhibition showing the general plan of restoration of Pyongyang was held at the Moranbong Underground Theater", the air raid shelter of the government under Moranbong. "On the way of victory... fireworks which streamed high into the night sky of the capital in a gun salute briefly illuminated the construction plan of the city which would rise soon with a new look". After the war, the city was quickly rebuilt with assistance from the Soviet Union, and many buildings were built in the style of Stalinist architecture. The plans for the modern city of Pyongyang were first displayed for public viewing in a theatre building. Kim Jung-hee, one of the founding members of the Korean Architects Alliance, who had studied architecture in prewar Japan, was appointed by Kim Il Sung to design the city's master plan. Moscow Architectural Institute, designed the "Pyongyang City Reconstruction and Construction Comprehensive Plan" in 1951, and it was officially adopted in 1953. The transformation into a modern, propaganda-designed city called Stalin style architecture with a Korean-style arrangement (and other modernist architecture that was said to have been greatly influenced by Brazilian architect Oscar Niemeyer) began. and in the 1972 Constitution it was officially declared as the capital.
