Russian photographer Arseniy Kotov intends to document these buildings and their surroundings before they are lost forever. He likes to take pictures in winter, during the ‘blue hour’, which occurs immediately after sunset or just before sunrise. At this time, the warm yellow colours inside apartment block windows contrast with the twilight gloom outside. To Kotov, this atmosphere reflects the Soviet period of his imagination. His impression of this time is unashamedly idealistic: he envisages a great civilization, built on a fair society, which hopes to explore nature and conquer space.
