Yes, Big Ben, like many historical monuments, is affected by pollution. The accumulation of soot and other pollutants in the air can lead to discoloration and deterioration of the stonework. Efforts are made to clean and restore the clock tower periodically to mitigate these effects and preserve its iconic appearance. However, ongoing air quality issues in urban areas continue to pose a challenge for such heritage structures.
