The city of Bath, in my opinion the most beautiful place in the world, is a world heritage site. The entire city is protected. Banning commercial activities there would effectively turn it into a backwater.

These sites were built bearing great costs and are representing our national glory.

Opening them up to commercial events provides funding for their maintenance.

When such shows are organised, it causes great damage to these relics which were built centuries ago.

That would depend upon how well these "relics" are maintained. I have visited many castles which are open to the public, and the income generated has kept them in far superior condition than would otherwise be possible.

Young people inscribe their names along with their loved ones onto the stone and walls damaging property.

The curious habit of leaving "cadenas d'amour" (padlocks of love) secured to bridges in France has resulted in massive clusters of padlocks inscribed with the names of lovers. In a few hundred years, they may themselves be regarded as world heritage sites.

To a significant extent, thievery is also reported which sums up to lakhs of loss!

I have not heard of these reports, but if thievery is indeed practiced, then the remedy is increased security.

It seems to me that a World Heritage Site gains its status for being an important part of the history of our world-story. That story continues today, and includes the events and festivals currently being held in the shadows of World Heritage Sites. To ban such events would actually decrease the value of the World Heritage Site, because it would in effect send the message that these sites no longer serve as a stage for the drama of human life, an are therefore no longer an important part of our story.

Reverence for history is important, but I believe that a historical monument retains its value insofar as it continues to affect human life.
