'Fixing' things

Most Indian historical sites will display a notice informing people of the statutory protection for historical buildings in India. Damaging the sites is punishable, 'fixing' them however does not seem to be. How many beautiful rock-cut caves and temples are partially cemented over to make steps. Or where the stones crack, someone has helpfully filled it with bits of off-colour cement which I doubt adds a single structural benefit to the 1000 ton building. The sites cannot be damaged but railings and lighting can be added... in fact this kind of thing is included under the banner of 'tourist development'. How I longed to have seen the renovated temple in the forest in its 'overgrown' state...
