The Red Fort faces several challenges regarding its preservation and maintenance. One of the primary issues is pollution, particularly from the surrounding urban environment, which poses a significant threat to the fort's structure and aesthetics. The accumulation of dirt and grime on the sandstone walls can lead to deterioration over time. Additionally, the increasing number of visitors can strain the infrastructure and resources required for upkeep. There are also concerns about the impact of climate change, including rising temperatures and extreme weather conditions, which can further exacerbate the wear and tear on the fort. To address these challenges, the Archaeological Survey of India and various conservation organizations are working on restoration projects and implementing measures to mitigate pollution and ensure the fort's longevity for future generations.
