Abandoned sites are locations that were once occupied or used but have been left empty and neglected. These places can include old factories, schools, houses, and even entire towns. Over time, nature often reclaims these areas, leading to the deterioration of buildings and infrastructure. Many abandoned sites hold historical significance, offering insights into past lifestyles and industries. They can attract urban explorers and photographers who are interested in capturing the beauty of decay. Some well-known examples of abandoned sites include Chernobyl, Pripyat, and Detroit's industrial areas.
