Abandoned cities are places where people once lived but have since left, often due to economic decline, natural disasters, or war. These areas can be found all over the world, with notable examples like Pripyat in Ukraine, which was evacuated after the Chernobyl disaster, and Pompeii in Italy, buried by a volcanic eruption. Many abandoned cities are now popular tourist attractions, drawing visitors interested in history and urban exploration. They often feature crumbling buildings, overgrown streets, and remnants of daily life, providing a glimpse into the past and sparking curiosity about the reasons for their decline.
