Key Insights:

• Top Heavy: The Forbidden City, which holds the top spot, strictly enforces flow limits. Without these caps, its potential volume would be even higher.
• Geographic Concentration: The top 3 sites are all located in Asia, highlighting the global appeal of Eastern historical culture.
• Data Context: Many sites now implement strict 'daily capacity limits' to ensure Sustainability, meaning the current ranking often reflects management thresholds rather than raw, unconstrained visitor demand.
