One of the most difficult decisions that any archaeological or historical site has to make is over public access to the site. How much traffic can those fragile resources take before they begin to deteriorate so much that preserving them means prohibiting people from seeing them? The Ajanta Caves recently decided to close four caves to protect them. While this affects the ability to educate the public, we think it was the right decision. These sacred sites are too precious to watch them fade into the dust.
