An abandoned amusement park (top) and the dilapidated Palace of Culture Energetik (bottom left) in Pripyat, Ukraine, near the site of the Chernobyl Nuclear Power Plant. Pripyat was home to nearly 50,000 residents before an explosion in April 1986 forced the evacuation of the town and the relocation of all people within a 30-kilometer radius of the plant. Overall, nearly 335,000 were displaced. Bottom right, A tourist visits a deserted building in the Chernobyl exclusion zone, 2011.
