CHERNOBYL, UKRAINE - MARCH 16: A general view shows the current state of the 30-kilometer Chernobyl Exclusion Zone. Established in the aftermath of the 1986 nuclear disaster at the Chernobyl Nuclear Power Plant, the 2,600-square-kilometer restricted area remains under strict state control. Forty years after the accident, the zone encompasses abandoned urban and rural settlements, the New Safe Confinement (NSC) structure, and the Chernobyl Biosphere Reserve. Since 2022, the territory has been designated as a high-security area due to its proximity to the border and the ongoing Russian-Ukrainian war on March 16, 2026 in Chernobyl, Ukraine.
